Both angles makes up the right angle or 90*. So…
Set the two expression added together equal to 90.
2x+2 + x+1 =90
Combine like terms.
3x+3 =90
3x=87
X= 29
Take x and substitute back into each expression to get the two angles.
2(29) +2 = 60*
29+1 =30*
The angles are 60* and 30* respectively.
Note that these angles add back to 90* or the measurement of a right angle.
