Answer:
3n + 7 + n and 4n + 7
Step-by-step explanation:
40
Use the Outside Angles Theorem,
B=8
B/4=B-6/4
4B=16B-96
96=12B
E. 35°, 70°
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°
