Step-by-step explanation:

SOLUTION:-

Mate as we know the angle made by a straight line is 180°

so,as per the question,

3x°+x°+90°=180°

=>4x°=180°-90°=90°

=>x=90°/4=22.5°

mark as brainlist plz

Answer 2

3x + x + 90 = 180

4x + 90 =180

4x = 180 - 90

4x = 90

x = 90÷4

x = 22.5

4x = 22.5 ×4 = 90

so,x = 22.5

and 4x = 90
