2. What is the length of
side c? Someone help

Side c has a length of √145, or approximately 12.04.

Step-by-step explanation:

Because this is a right triangle, you can use the Pythagorean theorem to solve it.  In a right triangle, the sum of the squares of the two sides is equal to the square of the hypotenuse.  Or in this example:

c² = 9² + 8²

So we can solve it:

c² = 9² + 8²

c² = 81 + 64

c² = 145

c = √145

c ≈ 12.04

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d
