Help me please just need this last one and I’ll be done please help me if you can

Answer 1

Answer:

58°

Step-by-step explanation:

Start with the equation 2x + 2 + 90 = 148

( I got the 90 from Angle B since it is a right angle.)

Combine like terms 2x + 92 = 148

( 90 and 2 didn't have variables so you could add them together.)

Subtract 92 from both sides 2x + 92 = 148

                                                      -92   -92

(The opposite of addition is subtraction.)

Now write out the new equation 2x = 56

Divide both sides by 2 $\frac{2x}{2}$ = $\frac{56}{2}$

You'll end up with... x = 28

To find the measure of angle BAC, plug in 28 where the x value is 2(28) + 2

This gives you the answer 58°
