Answer 1

Answer:

The answer is B.

Step-by-step explanation:

In a linear pair, the total angles is 180°. So we can form an expression for both angles. Let x be the smaller angle and 8x be the larger angle :

x + 8x = 180°

9x = 180°

x = 180° ÷ 9

x = 20°

Next, we have to substitute the x value into the larger angle expression :

8x = 8 × 20° = 160°
