Answer:

A. X is 6 and B. Angle is 50

Step-by-step explanation:

PART A

Triangle sum theorem explains that all angles in a triangle add up to 180

(8x + 2) + 70 + 60 = 180

8x= 180-70-60-2

8x= 48

X= 48/8 =6

PART B

Using the formula provided, replace the x with 6

So it'll be 8(6)+2 = 48+2 = 50

Answer:

a) x = 6° b) m∠B = 50°

Step-by-step explanation:

(a) total angle measure of a triangle is 180°

8x + 2 + 70° + 60° = 180°

8x + 132° = 180°

8x = 180° - 132°

8x = 48°

x = 6°

(b)

m∠B = 8x + 2

m∠B = 8(6) + 2°

m∠B = 48° + 2°

m∠B = 50°
