Consider the figure below, where line a is parallel to line b: Angle 4 = 12m - 4
Angle 5 = 10m + 20
Calculate the measure of Angle 5.

Angle 5= 140

Step-by-step explanation:

I assume you are talking about parrallel lines and a transversal. If that is the case, I can guess that angles 4 and 5 are alternate exterior angles. Therefore they are congruent.

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
