Answer 1

∠ 4 = 52°

Explanation:

The 3 angles lie on a straight line and sum to 180°, that is

90 + ∠ 3 + ∠ 4 = 180, substitute ∠ 3

90° + 38° + ∠ 4 = 180°

128° + ∠ 4 = 180° ( subtract 128° from both sides )

∠ 4 = 52°

Answer 2

the measure of angle 4 is 52 degrees.

Explanation:

The measure of angles 3 and 4 added together is 90 degrees. Angle 3 is 38 degrees. 90-38=54.
