What is rhe answer to this question?

40°

Step-by-step explanation:

To solve for x:

Turn this into an algebraic expression: (4x + 12) + (6x + 8) = 90Combine like terms: (4x + 6x) + (12 + 8) = 90Simplify: 10x + 20 = 90Subtract 20 from each side, so it now looks like this: 10x = 70Divide each side by 10 to cancel out the 10 next to x. It should now look like this: x = 7

Plug the value of x in, to solve for angle m∠1:

4(7) + 12Multiply: 4(7) = 4 × 7 = 28Plug 28 in: 28 + 1228 + 12 = 40°
