Answer:
![50^{\circ}](https://tex.z-dn.net/?f=50%5E%7B%5Ccirc%7D)
Step-by-step explanation:
Complementary angles mean that the sum of the angles add up to
. We can use algebra to solve for
and then to determine
.
![m\angle QRS + m\angle SRT = 90](https://tex.z-dn.net/?f=m%5Cangle%20QRS%20%2B%20m%5Cangle%20SRT%20%3D%2090)
![8x+10 + 8x = 90](https://tex.z-dn.net/?f=8x%2B10%20%2B%208x%20%3D%2090)
![16x = 80](https://tex.z-dn.net/?f=16x%20%3D%2080)
![x = 5](https://tex.z-dn.net/?f=x%20%3D%205)
![m\angle QRS = 8x+10](https://tex.z-dn.net/?f=m%5Cangle%20QRS%20%3D%208x%2B10)
(substitution)
![=50^{\circ}](https://tex.z-dn.net/?f=%3D50%5E%7B%5Ccirc%7D)
∴
