Question

The information given represents lengths of sides of a right triangle with c the hypotenuse. Find the correct missing length to the nearest hundredth. A calculator may be helpful.

a = ?, b = 12, c = 19

A.
14.03

B.
14.38

C.
14.73

D.
15.07

Answer 1

familiar with Pythagorean?

Answer 2

Wait

Answer 3

is the answer going to be c?

Answer 4

Use the Pythagorean Theorem.

a^2 + b^2 = c^2

a^2 + 12^2 = 19^2

Simplify the exponents:

a^2 + 144 = 361

Subtract 144 to both sides:

a^2 = 217

Find the square root of both sides:

a = 14.73
