Answer:
y = 1
Step-by-step explanation:
6 = 2y + 4
6 - 4 = 2y
2 = 2y
y = 2/2
y = 1
I think the answer is (x+1)(x-2)(x-3)
First we add all the angles together
x + 2x - 20 + 2x + 10 = 5x - 10
Now, you should know that all the angles in a triangle add up to 180°
180 = 5x - 10
Move the 10 to the other side
190 = 5x
Divide both sides by 5
x = 38
So the angles sizes in ascending order are
38 , 46 , 86
To find this you have to divide 351 by 46, which is <span>7.63043478261 but you can round it to 8. So it would be 8.</span>
It would be 8R7. 8x8=64. 71-64=7
