Find the value of x.
Please somebody help!!

The angle measuring 122 degrees is supplementary to the angle next to it.

Supplementary angles are angles that add up to 180 degrees.

180 = ? + 122

Subtract 122 from both sides.

58 = ?

Now we know that the triangle has a 58 degree angle and a 90 degree angle.

58 + 90 + x = 180

Combine like terms.

148 + x = 180

Subtract 148 from both sides.

x = 32 degrees

answer is  

a.

93.98 sq. in.

hope you got it chief
