Answer:
x = 12
Step-by-step explanation:
We know that the total angle measure of a triangle is 180 degrees, so the sum of all the angles should be 180 degrees.
Therefore, we can add all the angles, set them equal to 180 and solve for x
2x+5 + 6x-5 + 7x = 180
We can combine all the x terms and all the numerical terms on the left side of the equation to get:
(2x+6x+7x) + (5-5) = 180
15x = 180
Then we can divide both sides by 15 to isiolate x
15x = 180
x = 180/15 = 12
Answer: Are you high school because GOD that looks hard to do.
Step-by-step explanation:
Answer:
To start, the slope is -2.
To solve for the slope you want to take two coordinates, lets say (1, -1) and (0,1) you would want to plug them into the slope formula.
This is
(1, -1) is coordinate one. Which means 1 = and -1 is =
And
(0,1) is coordinate two. Which means 0 = and 1 is = \
If you put in the values you will get
Therefor, the slope is -2.
X + 17 = 3x -31 (opposite angles are equal)
x + 17 = 3x -31
31 +17 = 3x - x
48 = 2x
x = 24
