Answer:
x = 5.2
Step-by-step explanation:
Let's first simplify our first function:
Now, we just need to set this function equal to our other given function.
Now, we can add 12 to both sides:
Now, add 5x to both sides:
Finally, we'll divide both sides by 5:
Answer: x = 5.2

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°
