Question

Angle D=(7b+1) angle E=(2b+1) and angle F=(b+8) what is the measure of angle E

Answer 1

<E = 35

Explanation:

7b + 1 + 2b + 1 + b + 8 = 180

combine like terms

7 + 2 + 1 = 10

10b

1 + 1 + 8 = 10

10b + 10 = 180

substract 10 from 180

= 170

10b = 170

170 divided by 10

= 17

now plug in for b for angle E

2 (17) + 1

= 35

Answer 2

angleD=(7b+1)angle E=(2b+1)and angle F=(b+8)
