Answer:

m∠A = 101*

Explanation:

m∠A = (25x + 1)*

m∠B = 82*

m∠C = (25x - 2)*

m∠D = (20x - 1)*

Find m∠A. Key: solve for x

(25x + 1) + 82 + (25x - 2) + (20x - 1) = 360*

Subtract 82 from both sides

(25x + 1) + (25x - 2) + (20x - 1) = 278*


x = 4

Now substitute x for 4 in A measure

(25x + 1)

(25(4) + 1)

(100 + 1)

101

m∠A = 101*

Answer:

D. 101

Explanation:

(25x+1)+(25x-2)+(20x-1)+82=360

70x=360-1+2+1-82

70x=280

x=4

A=25x+1=101
