Answer:

$50^(\circ)$

Explanation:

Complementary angles mean that the sum of the angles add up to
$90^(\circ)$ . We can use algebra to solve for
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 :)
