Answer:

1) x= 20

2) x= 75

Explanation:

In the first problem, we see vertical angles. This means that both angles equal each other: 50= 2x+10

Step 1- Subtract 10 to both sides.

50= 2x+10

-10 -10

40= 2x

Step 2- Divide both sides by 2.

40= 2x

2 2

x= 20

In the next problem we see a straight line and an intersecting point. Now, both of these angles sum up to 180 degrees. So the equation would be:

x-10+2x-35= 180

Step 1- Add common variables.

(x+2x)+(-10-35)= 180

3x-45= 180

Step 2- Add 45 to both sides.

3x-45= 180

+45 +45

3x= 225

Step 3- Divide both sides by 3.

3x= 225

3 3

x= 75

Input the value of x into the equations.

75-10= 65

2(75)-35= 115

Hope this helps!
