Answer:
Set up an equation equal to <span>180o</span>
Explanation:
<span>3x+3x+6x=180</span>
<span>12x=180</span>
<span>x=<span>18012</span>=15</span>
So, the measure of the angles are:
<span>3x=3×15=45</span>
<span>3x=3×15=45</span>
<span>6x=6×15=<span>90</span></span>

Step-by-step explanation:
the answer is d the image is the same size
For this case we have the following equation:

We must clear the variable "x":
We multiply by 2 on both sides of the equation:

We divide by h on both sides of the equation:

We subtract "a" on both sides of the equation:
