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 [tex]\frac{2x}{2}[/tex] = [tex]\frac{56}{2}[/tex]
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°
