4(3A - 4) = 56
first distribute 4
12A - 16 = 56
then add 16
12A = 72
finally, divide by 12
A = 6

Answer:

A = 6

Step-by-step explanation:

First, use the distributive property on the left side:

4(3A - 4) =56\\12A - 16 = 56

Add 16 to both sides

12A = 72

divide both sides by 12

A = 6

ella [17]

Answer:

m\angle Y=40^\circ

Step-by-step explanation:

Suppose we have a triangle WXY whose internal angles are:

m\angle W = 10x+17

m\angle X=2x-9

m\angle Y=3x+7

The sum of the measures of the angles must be 180°, thus:

10x+17 + 2x-9+3x+7=180

Simplifying:

15x + 15 = 180

Subtracting 15:

15x = 165

Dividing by 15:

x = 11

Thus, the measure of angle Y is

m\angle Y=3x+7=3*11+7=33+7=40

\mathbf{m\angle Y=40^\circ}
