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: the value of x is 15°
Step-by-step explanation:
A is 2x. B is 2(2x), so 4x. C is 3(2x) so 6x.
The sum of all the angles of a triangle is 180°
Set up the equation:
2x + 4x + 6x = 180
12x = 180°
x = 15°
