Answer:
The answer is 72.32°
Step-by-step explanation:
So, since that is a straight line, we know that all of the angles add up to get 180° total. Using this knowledge, we can determine that 44.4 + 8x + 7x = 180°.
First, we need to find what x is to find the missing values. To do that, we have to set all the values, 44.4, 8x, and 7x equal to 180, because we know they add up to 180°.
44.4 + 8x + 7x = 180
Combine the like terms.
44.4 + 15x = 180
Bring the 44.4 over to the other side in order to get x alone by subtracting it from 180.
15x = 135.6
Divide both sides by 15 to get x completely alone.
<u>x = 9.07</u>
Now we have what x is, 9.07.
All you need to do now is substitute 9.07 into the place of x.
8(9.07) = 72.32
So now you know that the highlighted angle is 72.32°.
