Answer:
Step-by-step explanation:
x+x+1/2 x+1/2 x=360
3x=360
x=360/3=120
1/2 x=1/2×120=60
60,60,120,120
Additive inverse of a number is the number that should be added to the number to result in zero.
Eg additive inverse of -2 is +2, because -2 + 2 = 0
Similarly additive inverse of - 10 1/4 is +10 1/4.
Answer:
-3/4 slope
Step-by-step explanation:
y = 3/4 x +2 has a slope of 3/4
Perpendicular lines intersect.
So the slope of the perpendicular line must be opposite.
