Answer:
74
Explanation:
Since a triangle always has a total of 180 degrees when its angles are added, we can start by subtracting 32 from 180
180 - 32
180 - 32 = 148
The two lines that are 7.2 units are both equal, so the angles will also be equal. After subtracting 32 from 180, we have 148 left between the other two angles.
Knowing this, we can divide 148 by 2, to solve for x.
148 / 2 = x
148 / 2 = 74
x = 74
