Construct A Right Triangle Whose Hypotenuse And One Side Measures 10 Cm And 8 Cm Respectively., Then Construct Another Triangle Whose Sides Are 4 /5 T

Construct a right triangle whose hypotenuse and one side measures 10 cm and 8 cm respectively.

Then construct another triangle whose sides are 4 /5 times the corresponding sides of this triangle

 

ANSWER:

Use the following information to draw the similar right triangles:

The hypotenuse and sides of the big right triangle are 10 cm,  8 cm and 6 cm, respectively.

The hypotenuse and corresponding sides of the small right triangle are 8 cm, 6.4 cm and 4.8 cm.

Step-by-step explanation:

Similar triangles have proportional sides.

The scale factor or ratio of small triangle to big triangle is 4/5 or 4:5.

The given measurements are sides of the big triangle because the small triangle is only 4/5 of the corresponding sides of the given right triangle:

Given measurements of big right triangle:

hypotenuse (the longest side of the right triangle): 10 cm

Side₁: 8 cm.

Find Side₂ using Pythagorean Theorem:

c² = a² + b²

Where c = hypotenuse, and  a and b = sides 1 and 2, respectively.

10² = 8² + b²

b² = 100 - 64

b = √(36)

b = 6  ⇒ Side₂ of the big triangle

Therefore, the hypotenuse and sides of the big right triangle are 10 cm,  8 cm and 6 cm, respectively.

Find the side of the small triangle which is 4/5 of the sides of the big right big triangle:

hypotenuse = (4/5)(10) = 8 cm

side₁ = (4/5)(8) = 32/5 or 6 ²/₅ cm  or  6.4 cm

side₂ = (4/5)(6) = 24/5  or  4 ⁴/₅ cm  or  4.8 cm.

Therefore, the hypotenuse and corresponding sides of the small right triangle are 8 cm, 6.4 cm and 4.8 cm.

Check:

Hypotenuse:

8:10 = 4:5

4:5 = 4:5  (True)

Side₁:

6.4 : 8 = 4:5

Multiple each value at the right side of equation by 10:

64 : 80 = 4:5

Divide each value at the right side by 16, its GCF:

4:5 = 4:5   (True)

Side₂:

4.8 : 6 = 4:5

Same procedure in checking as side 2:

48 : 60 = 4:5

4:5 = 4:5 (True)

Buod nga kabanata 22   Kabanata XXII Liwanag at Dilim Buod Magkasamang dumating si Maria at ang kanyang Tiya Isabel sa San Diego para sa pistang darating. Naging bukambibig ang pagdating ni Maria Clara sapagkat matagal na siyang hindi nakakauwi sa bayang sinilangan. Isa pa, minamahal siya ng mga kababayan dahil sa kagandahang ugali, kayumian at kagandahan. Labis siyang kinagigiliwan ng mga ito. Sa mga taga-San Diego, ang isa sa kinapapansinan ng malaking pagbabago sa kanyang ikinikilos ay si Padre Salvi. Lalong pinag-usapan si Maria Clara, nang dumating si Crisostomo Ibarra at madalas na dalawin ito. Sinabi ni Ibarra kay Maria Clara na handa na ang lahat para sa gagawin nilang piknik kinabukasan. Ikinatuwa ito ng dalaga sapagkat makakasama na naman niya sa pamamasyal ang kanyang dating mga kababata sa bayan. Ipinakiusap ni Maria Clara sa kasintahan na huwag ng isama ang kura sa lakad nila sapagkat magmula ng dumating siya sa bayan nilulukob siya ng pagkatakot sa tuwin...

A Group Of 4 Soldiers,6 Policeman, And 5 Generals Are To Be Seated In A Row Of 15 Seats.In How Many Mays Can They Be Seated Given The Following Condit

Image
A group of 4 soldiers,6 policeman, and 5 generals are to be seated in a row of 15 seats.In how many mays can they be seated given the following conditions: 1. The generals are to be seated next to each other. #2. Two of soldiers are on one end and the other two on the other end of the row. #3. The policeman are seated in a consicutive seats.   Answer: Step-by-step explanation: Condition #1: Generals are to be seated next to each other. Take the 5 generals as a single unit and there will 11 factorial arrangements which will be multiplied to 5 factorial ways between the generals. 11! × 5! = (11×10×9×8×7×6×5×4×3×2×1)(5×4×3×2×1) = (39,916,800)(120) = 4,790,016,000 Condition #2: Two of soldiers are on one end and the other two on the other end of the row. Consider the 2 soldiers on one end and the 2 on the other end as a single row of 4 seats. Let 4 factorial stand for their arrangements to be multiplied by 11 factorial ways of 6 policemen and 5 generals in the remaining 11 seats. 4!...

Ano Ang Layunin Ng Gobyerno Bakit Kailangan Pang Ibaba Sa 12 Ang Minimum Age Of Criminal Responsibility/Liability

Ano ang layunin ng gobyerno bakit kailangan pang ibaba sa 12 ang minimum age of criminal responsibility/liability   MANILA, Philippines – Senate President Vicente Sotto III on Monday, February 4, hit critics of the bill seeking to lower the minimum age of criminal responsibility to 12 years old, saying the proposal is "pro-poor." (READ: Beyond juvenile delinquency: Why children break the law) "Some would say that the proposed measure is anti-poor since most of the children in conflict with the law and the children at risk come from families that have no meaningful access to legal services," Sotto said in his speech as co-sponsor of the bill. "To this, I say: actually this proposal is pro-poor. Since children in poor families do not have access to quality education and are being exposed to violence in their own family and communities, the government is stepping in to provide these children with education and training. Their parents failed to attend to...
