Answer:
180˚ or C
Step-by-step explanation:
Complementary angles are two angles that add up to 90˚.
Since m∠A = 40˚ then we can write and equation where ∠B equals x.
40 + x = 90
40 - 40 + x = 90 - 40
x= 50
m∠B = 50˚
Supplementary angles are two angles that add up to 180˚.
Since ∠B is the supplement of ∠C, we will use x as the value of ∠C.
50 + x = 180
50 - 50 + x= 180 - 50
x= 130
So ∠C = 180˚
Thus, 50˚ + 130˚ = 180˚
Answer:
B
Step-by-step explanation:
b and a=40⁰ so if b+c is supplementary they equal 180⁰ together so 180-40= 150⁰

Answer:
-1/4
Step-by-step explanation:
Take two points on the line
(-4,-1) and (0,-2)
Using the slope formula
m = (y2-y1)/(x2-x1)
= ( -2 - -1)/( 0 - -4)
= (-2+1)/ ( 0+4)
-1/4
