Answer:
D
Step-by-step explanation:
This is a Pythagorean Theorem application.
Givens
a = ?
b = 24
c = 74
Formula
a^2 + b^2 = c^2
Solution
a^2 + 24^2 = 74^2
a^2 + 576 = 5476 Subtract 576 from both sides.
a^2 +576-576 = 5476- 576 Subtract
a^2 = 4900 Take the square root of both sides.
sqrt(a^2)=sqrt(4900)
a = 70
