Question

What does side b equal?

Answer 1

Answer: 7.2

Step-by-step explanation:

Since this is a right triangle we can use the Pythagorean theorem to solve for side b.

Pythagorean theorem: a²+b²=c²

Since the side length opposite the right angle is the hypotenuse we plug 11.2 in for C

(8.6)² + b²=(11.2)²

73.96 + b² = 125.44

b²=51.48

b = 7.17495644586

b=7.2

Answer 2

Answer: 8.6

same side s C and B
