Question

Can You Please Give The Answers With Explaination? I Need It For My Homework I Would Be Grateful!

Answer 1

Step-by-step explanation:

for e :-

x + 2x + 90° = 180°

3x = 90°

x = 30°

x = 30° & 2x = 2×30 = 60°

for f

(x+20°)+30° + 90° = 180°

x + 20° + 30° + 90° = 180°

x + 140° = 180°

x = 40°

(x+20) = 40+20 = 60°

for g

x + y + 90° = 180°

45° = x (( opposite angle ))

45°+90°+y = 180°

y = 45°

for h

a° + 140° = 180° (( Linear pair ))

a = 40°

now, a°+b°+90° = 180°

40° + b° + 90° = 180°

b = 50°
