Question

What are the values of two angles shown in the figure given below?
18° and 252°
30°and150°
45°and138°
60° and 120°​

Answer 1

Answer:

42 and 138

Step-by-step explanation:

3x+12x-30=180

15x-30=180

15x=180+30

15x=210

x=210/15

x=14

1st angle=3x=3*14=42

2nd angle=12x-30=12*14-30=168-30=138

The ans should be 42 and 138, so I think the 3rd option has a small mistake, otherwise it is the 3rd option.
