Answer 1

`50^(\circ)`

Explanation:

Complementary angles mean that the sum of the angles add up to
`90^(\circ)`. We can use algebra to solve for
`x` and then to determine
`m\angle QRS`.

`m\angle QRS + m\angle SRT = 90`

`8x+10 + 8x = 90`

`16x = 80`

`x = 5`

`m\angle QRS = 8x+10`

`= 8(5)+10` (substitution)

`=50^(\circ)`

∴
`m\angle QRS = 50^(\circ)`

Hope this helps :)
