Useful Information:
Co-interior angles add to 180°
Step-by-step explanation:
The first step is to add 4x to 5x, which gives you 9x. This is because co-interior angles add up to 180, so 4x+5x=180. Co-interior angles can be spotted by their C shape.
To work out the value of x you would need to divide 180 by 9, which gives you 20°. This is because 9x is equal to 180. This means that x is equal to 180 divided by 9.
1) Add 4x to 5x.

2) Divide 180 by 9.

Answer:
6x4=24 as a fraction it could be 24/1 48/2 72/3 etc.

Answer:
Step-by-step explanation:
hello :
the point-slope formula is :
y - y_1 = m(x - x_1) the point is A(x_1 , y_1 ) , m : the slope
in this exercice : x_1 = -1 y_1 = 4 m = 3
so : y - 4 = 3(x +1) ...an equation for this line .
I believe it is A because if you find the volume and area of each shape, you get 72
