Pretty sure its D. you need to divide 60.5 by 69
J=john
m=mary
j is 2 times as old as mary
j=2 times m
sum is 21
m+j=21
find mary
subsitute
j=2m therefor subsitute 2m for j
m+2m=21
add like terms
3m=21
divide by 3
m=7
mary=7

Answer:
D.64
Step-by-step explanation:
A linear line equals up to 180
A+D=180
Substitute 116 for A
116+D=180

D=64
A reflection across the x-axis won't change the measure of an angle
The answer is 64.
