Supplementary angles add to 180 degrees.

Angles of a triangle add to 180 degrees.

So, the angles of this triangle are 2x, 3x, and 70.

This means we can have the equation: 5x+70=180, and 5x=110, meaning that x=22

Let  me know if this helps!

22

Step-by-step explanation:

So first things first we want to find the angle on the bottom right

That angle is supplementary to the one that is equal to 110 meaning that together they will add up to equal 180

180-110=70

We know that the angles of a triangle will add up to equal 180 so we set up an equation

180=70+2x+3x and solve for x

step 1 combine like terms

2x+3x=5x now we have

180=70+5x

step 2 subtract 70 from each side

180-70=110

70-70 cancels out

now we have

110=5x

step 3 divide each side by 5

110/5=22

5/5 cancels

x=22

so we can conclude that x=22

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3
