Every triangle measures 180 degrees.
In order to get the answer you need to add every equation and set it equal to 180.
2x+4+2x-9+x=180
Combine like terms.
5x-5=180
Add 5 to the other side.
5x=185
Divide by 5.
x = 37
Now, plug 37 in for every x.
Angle A: 2(37)-9
Angle B: 2(37)+4
Angle C: 37
The measures are:
Angle A = 65
Angle B = 78
Angle C = 37
Hope this helps!

Answer:
y = -4x - 24
Step-by-step explanation:
Firstly, figure out the slope. To do that, plug the coordinates in the formula.
y2 - y1 / x2 -x1
= -24 - 0 / 0 - (-6)
= -4
The slope is -4/1x.
To figure out the y-intercept, you need to plug one of the coordinates into
y = -4x + b
0 = -4(-6) + b
0 = 24 +b
-24 = b
Given that the associative property of multiplication says that you can group the numbers in any combination, we can reorganize the expression as: 7·(10·3)=210. So the answer would be the first option.
