Find the missing lengths of the sides.
Anarel [89]

Given:

The figure of a right angle triangle.

a=b

Hypotenuse = 9\sqrt{2} in.

To find:

The missing lengths of the sides.

Solution:

In the given right angle triangle both legs a and b are equal, and hypotenuse is 9\sqrt{2} in.

Using Pythagoras theorem, we get

Hyponteuse^2=Base^2+Perpendicular^2

(9\sqrt{2})^2=(a)^2+(b)^2

81(2)=(a)^2+(a)^2                    [\because a=b]

81(2)=2(a)^2

Divide both sides by 2.

81=(a)^2

Taking square root on both sides.

\pm \sqrt{81}=a

\pm 9=a

Side cannot be negative. So,

9=a

Thus, the missing side lengths are a=9 in and b=9 in.

Therefore, the correct option is C.

Can someone solve and explain
S_A_V [24]
The answer is F.30
Explanation: If we do guess and check, if we multiply the ratios by 10, it would be 30:40:50, which doesn’t add up to 180 degrees. if we multiply the ratios by 20, It would be 60:80:100, which also doesn’t add up to 180 degrees. How about we multiply the ratios by 15? It would be 45:60:75, which does add up to 180! The difference between x and z is 30, so the answer is F.30
