Question

Using the Pythagorean theorem, find the measure of the hypotenuse when a = 7.2m and b = 5.5m.
A. 6m
B. 9m
C. 12m
D. 13m

Answer 1

a^2+b^2=c^2
so (7.2)^2+(5.5)^2=c^2
82.09=c^2
find the square root
9.060

Answer 2

a^2 + b^2 = c^2

c = sqrt( a^2 + b^2)
c = sqrt( 7.2^2 + 5.5^2) solve

Answer 3

do \[a^2+b^2=c^2\]

Answer 4

a=7.2
b=5.5

now plug in!
