Answer:
41
Explanation:
In order to find the measure of angle C we must find the value of x
Remember the measures of the angles in a triangle add up to equal 180
that being said we use this equation to solve for x
180 = (sum of angles) 63 + 2x + 8 + x + 7
now we solve
step 1 combine like terms
63 + 7 + 8 = 78
2x + x = 3x
now we have 180 = 78 + 3x
step 2 subtract 78 from each side
180 - 78 = 102
78 - 78 cancels out
now we have 102 = 3x
step 3 divide each side by 3x
102/3=34
3x/3=x
we're left with x = 34
Now to find the measure of angle C
We plug in the value of x in the expression (x + 7)
so c = 34 + 7
34 + 7 = 41
therefore your answer is 41
