Question

please answer this...if possible..(in place of my sister)I really need it..​

Answer 1

Step-by-step explanation:

1) x=180-60=120°

2) 3x+2x=180°

5x=180°

x=36°, 3x=3×36=108°, 2x=2×36=72°

3) 35+x+60=180°

x=85°

4) x+47+75+92+83=360

x+297=360

x=63°

5) 2x+x+2x+3x=360

8x=360

x=45°, 2x=90°, 3x=135°

6) 3x=105°

x=35°

Answer 2

1) AOC = 180°

180 = 60 + x
X = 180 - 60
x = 120

2) POR= 180°

180° = 2x + 3x

180° = 5x

x= 180 divided by 5

x= 36

:- 180° = 2x + 3x
180° = 2*36 + 3*36
180° = 72 + 108
180 = 180

2x= 72

3x/ 108


3) LOM = 180°

180° = 35 + 60 + x

180° = 95 + x

x = 180 - 95

x = 85


4) O = 360°

360° = 83 + 92 + 75 + 47 + x

360° = 297 + x

x = 360 - 297

x = 63

5) O = 360°

360° = 2x + 3x + 2x + x

360° = 8x

x = 360 divided by 8

x = 45

6) 3x = 105° ( vertically opposite angles )

=> 105 = 3x

x = 105 divided by 3

x = 35

Hope it helps!!
