Answer:
m∠A = 101*
Step-by-step 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
Step-by-step explanation:
(25x+1)+(25x-2)+(20x-1)+82=360
70x=360-1+2+1-82
70x=280
x=4
A=25x+1=101
