#9 the sum of two angles is 90 degrees, creating a right angle.
#10 the sum of the two angles is 180 because the form a supplementary angle
Answer:
The answer would be the third one.
Answer:
t = 26
Step-by-step explanation:
Step 1: Subtract 9 from both sides.
Step 2: Check if solution is correct.
Therefore, t = 26.
So 4.75 times 42= 199.5 so take 240-199.5= 40.5 so he is correct
A = 2
b = 0
2a + 2b = 4 → 4a + 4b = 8
(4a + 4b = 8) - (4a - 3b = 8) → 7b = 0
b = 0
so a = 2
