Question

Measure (7x+1) (2x+1)

Answer 1

Answer:

-7 the mesaures. of the smaller

Answer 2

Smaller angle = 41°

Larger angle = 139°

Step-by-step explanation:

(7x - 1) + (2x + 1) = 180

7x + 2x - 1 + 1 = 180

9x = 180

x = 20

• The measure of the smaller angle is

2x + 1

= 2(20) + 1

= 40 + 1

= 41°

• The measure of the larger angle is

7x - 1

= 7(20) - 1

= 140 - 1

= 139°
