Answer 1

`\displaystyle \angle3 = {90}^( \circ)`

Explanation:

we are given two angles

we are want to figure out the missing angle

remember,

Straight line theorem

so we acquire

`\displaystyle \angle3 + \angle4 = {180}^( \circ)`

substitute the value of the given angle:

`\displaystyle \angle3 + {90}^( \circ) = {180}^( \circ)`

cancel 90° from both sides:

`\displaystyle \angle3 = {90}^( \circ)`

hence, the measure of the missing angle is 90°
