Question

For a given right angle, side a=76.4 ft and side b=39.3 . What is the length of side c to the nearest tenth of a foot?

Answer 1

Use the Pythagorean theorem.
a^2+b^2=c^2
In this case:
a=76.4
b=39.3
c=unknown variable
76.4^2+39.3^2=c^2
5,836.96+1,544.49=c^2
7,381.45=c^2
c=85.91536533
Round to the nearest 10th decimal= 85.9
