Need help with angles brainlest and points

14

Step-by-step explanation:

A, x=14

Step-by-step explanation:

We know that <HJL is a right triangle, therefore 90 degrees.

<HJK + < KJL = <HJL

<HJK + 50 = 90

<HJK = 40

We replace HJK with 3x-2

3x-2 =40

3x=42

x= 14, A

I hope this helped! :)

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a
