First you would add the 1/8 's together to get 2/8. Then simplify to 1/4. Lastly fill the last blank with 1/4.
1/4 + 1/4 + 1/4 = 3/4
Answer:

i hope this helped im only in the 8th grade, so i am just learning this
Complementary angles ⇒ the angles add up to 90°
∠A and ∠B are complementary ⇒ ∠A + ∠B = 90°
∠A + ∠B = 90°
Plug in the values for ∠A and ∠B:
(3x - 8) + (5x + 10) = 90
Open the brackets:
3x - 8 + 5x + 10 = 90
Combine like terms:
8x + 2 = 90
Subtract 2 from both sides:
8x = 88
Divide both sides by 8:
x = 11
Answer: x = 11
