What is the measure of angle x?

x = 60°

Step-by-step explanation:

We know that ∠H is 30° and we know that ∠J is 90° thanks to the red box. The sum of the angles of a triangle is 180°, so we can use this to solve for x.

x + 30 + 90 = 180

x + 120 = 180

x = 60

Therefore, it is 60°.

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

you can't solve x because it is 2 linear equation and you only have one equation
