Answer:
E. 35°, 70°
Step-by-step explanation:
Sum of angles add up to 180° in every triangle.
Step 1: Set up equation
a + 2a + 75 = 180
Step 2: Combine like terms
3a + 75 = 180
Step 3: Subtract 75 on both sides
3a = 105
Step 4: Divide both sides by 3
a = 35
So 1 angle is 35°
Step 5: Plug in <em>a</em> to find last angle
2(35) = 70°

Answer:
B and C
Step-by-step explanation:
5 * (7 + 6s - 9t) = 7*5 + 6s *5 - 9t*5
= 35 + 30s - 45t
(-35 - 30s + 45t)*(-1) = (-35)*(-1) - 30s *(-1) + 45t*(-1)
= 35 + 30s - 45t
