Step-by-step explanation:
The sum of the three angles in a triangle must be
. Since this triangle has a right angle, we know that it is
°, so the sum of the remaining two angles must be
.
We can set up an equation for the two remaining angles to determine the value of
:
![(x + 28) + x = 90](https://tex.z-dn.net/?f=%28x%20%2B%2028%29%20%2B%20x%20%3D%2090)
![2x + 28 = 90](https://tex.z-dn.net/?f=2x%20%2B%2028%20%3D%2090)
![2x = 62](https://tex.z-dn.net/?f=2x%20%3D%2062)
![x = 31](https://tex.z-dn.net/?f=x%20%3D%2031)
