Question

Please answer this question ​

Answer 1

Answer:

Sum of all angles =360°

130° +150° +ACB = 360°

280° +ACB=360°

ACB =360-280

ACB=80°

Answer 2

Step-by-step explanation:

In triangle AOC,

x+x+130=180

2x=180-130

x=50°/2

x=25°

means angle ACO=25°

In triangle OCB,

x+x+150=180

2x=180-150

x=30/2

x=15°

means Angle OCB=15°

To find angle AngleACB=AngleACO+AngleOCB

=25°+15°

=40°

ANSWER Angle ACB=40°
