Question

For this right triangle, find the measure of angle g. angle g = ?°

Answer 1

The sum of the interior angles of all triangles is 180 degrees. This is a right triangle, thus we know two interior angle values (90 degrees and 29 degrees). To find the third, set the sum of all interior angle values equal to 180 and solve for g.

180 = 90 + 29 + g

Collect like terms.

180 = 119 + g

Subtract 119 from both sides.

61 = g

Find the sum using 61 for g to check work.

180 = 90 + 29 + g

180 = 90 + 29 + 61

180 = 180

Answer:

m∠g = 61°
