its B. 50°
Triangle Have 180°
- 180 - 90 = 90
- 90 × 2 = 180
Half of triangle Have 90°
Answer:
2
Step-by-step explanation:
The line is at 2. Everything below that is shaded in.
So y is less than 2.
I will go about solving this using the elimination method.
First, convert the equations.
10x + y = -20
4x + y = -12
Second, find the easiest variable to get rid of and get rid of it! (In this case, y) We will subtract to get rid of y.
6x = -8
Third, you want to solve the equation.
6x = -8 (divide by 6)
x =

Fourth, solve for y by inserting the answer for x into one of the equations.
10(

) + y = -20

+ y = -20 (subtract

)
y =

The solution for this system of equations is (
