I seen your comment on the other persons thing, it should be 60° :) correct me if i’m wrong!
83x+P=83x+Q
subtract 83x from each side
P=Q
if P does not Q there are no solutions
the lines would be parallel and never intersect if Q does not equal P
<span>B) y = -3x3

Answer: x=12
Step-by-step explanation:
we know that sum of a triangle is 180 degrees
one angle is 90 degree
the sum will be 90+(2x+1)+(5x+5)=180
substract 90 from both sides
2x+1+5x+5=180-90
7x+6=90
7x=90-6
divide by 7
x=12
The answer is 650 because 100 * 5 = 500 and 50 * 3 = 150 and 500 + 150 = 650
