Answer: The measures of the angles are 64.6 degrees and 25.4 degrees.
Step-by-step explanation:
Complementary angles add up to 90 degrees.
x can be one angle, and (x-39.2) can be the other
x + (x-39.2) = 90
2x - 39.2 = 90
add 39.2 to both sides
2x = 129.2
divide each side by 2
x = 64.6
find the measure of the other angle
64.6-39.2 = 25.4
The measures of the angles are 64.6 degrees and 25.4 degrees.

Person = 1 head and 2 legs
horse = 1 head and 4 legs
p +h = 74
p = 74-h
2p +4h = 196
2(74-h) +4h = 196
148-2h +4h = 196
148 +2h = 196
2h = 48
h = 48/2 = 24
24 horses
50 people
answer is B
