Answer: B. −9
Step-by-step explanation: -7--(-2)
−7+−2
−9
Straight lines will always add up to 180 degrees, so the angle that is missing here is supplementary to the other angle(adds up with the other angle to get 180) so we take 79 away from 180 and get 101 degrees
X+1825=y^2
sqrt（1825）=42.8
so the least is y^2=43^2=1849
so x=1849-1825=24
