If m<2=35° and <1and <2 form a right angle. Find m <1.
yaroslaw [1]
To solve this problem, we just need to set up a simple equation. We have that angles 1 and 2 add up to equal a right angle, or 90°, and that m<2 is 35°, so we just have to do a bit of subtraction.

<1 + <2 = 90   Given
<1 + 35 = 90   Substitute 35 for <2
<1 = 55°   Subtract 35 from both sides to get rid of it, since subtraction is the opposite of addition.

Therefore, m<1 = 55°.

Hope this helps!
