Question

two angle are adjacent and form angle of 150° . the smaller is 30° less than . [lines and angle]​

Answer 1

Answer:

Step-by-step explanation:

Given,

Let the first no. be x

so, 2nd no. is x-30°

an angle of 150°

So,

x + x - 30° = 150°

2x - 30° = 150°

2x = 150° +30°

2x = 180°

x = 180°/2

x = 90°
