Two angles are complementary. One angle measures 32 degrees more than the other angle. Find the measure of the LARGER angle

Goshia [24]

$\begin{array}{l}\text{We\ have\ } \alpha +\beta =90\ \text{and} \ \beta =\alpha +32\text{\ then}\\\\\alpha +\alpha +32=90\\\\\Longrightarrow 2\alpha =90-32\\\\\Longrightarrow \alpha =\frac{58}{2} =29\\\\\therefore \beta =29+32=61\\\\\therefore \boxed{\text{The\ larger\ angle\ is\ 61\ degrees}}\end{array}$

You have to place 1 on the y-axis to get (0,1) and then go down 2 from that point and right 3 and continue to do so until you have enough point. Then from (0,1) you have to go up 2 left three until you have enough points. Once you have done this you connect all the points together and that is your answer.
I hope this helps!
