Answer:
C
Step-by-step explanation:
C
Answer:
We know that opposite angle are congruent.
So, We found out that x = 7,
So, Putting x = 7 in 10x+10
So, The measure of angle 10x+10 is 80.
The quickest way to tell if a line is perpendicular is to find the slope, so you'll need to get the slope for both lines
PQ = ((-8) - (-9))/(2 - 0) = 1/2
and, for reference, a perpendicular slope is the negative reciprocal of the original (so we're looking for -2)
RS = (3 - 4)/(3 - 1) = -1/2
so, no, these two lines aren't perpendicular because the slope of RS is only the negative of PQ, not the negative <em>reciprocal</em>.
Solution
621 ÷ 7 = n
621 ÷ 7 = <span>88.7142857143

n = 88.7142857143
Answer = 88.7142857143
Rounded = 88.7
