Question

15. In the given figure find x​

Answer 1

Answer:

x=45

Step-by-step explanation:

180°=45°+x+15°+x+30°

180°=45°+2x+45°

180°=90°+2x

2x=180°-90°

2x=90°

x=90°

2

x=45°

1.x+15°=15°+45°=60°

2.x+30°=45+30°=75°

Answer 2

hey mate!

x + 15 + 45 + x + 30 = 180 degree ( straight angle)

so, 2x + 90 = 180

$2x \: = 180 - 90 = 90 \: degree$

$x \: = \frac{90}{2} = 45 \: degree$

hope this helps you!
