In a right triangle, one angle is equal to 90 degrees while the sum of the other two angles are also 90 degrees. In this case, x is a right angle, so it equals 90 degrees. We know that one of the other angles is 47 while the second is y. So, y+47=90. To find y, we subtract 47 from 90, which is 43 degrees. y=43 degrees.

<span>90+47=137 X is a right angle so it is going to equal 90 that is where the 90 came from.

180-137=43 to find y we have to subtract 180 (the sum of all triangles) by the sum of x and 47. Which ends up being 43.
X= 90
Y= 43</span>

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.
