Answer:
50
Step-by-step explanation:
The sum of the angles of a triangle add to 180 degrees
A + B + C = 180
2x-10 + 70+ x+30 = 180
Combine like terms
3x +90 = 180
Subtract 90 from each side
3x+90-90=180-90
3x= 90
Divide by 3
3x/3= 90/3
x=30
We want to find angle A
A = 2x-10
=2*30 -10
=60-10

Hey there!!
Given equation :
... 3x - 2 + 5x = 4x + 5 - 2x
Combining like terms :
... 8x - 2 = 2x - 5
Subtracting 2x on both sides :
... 6x - 2 = - 5
Adding 2 on both sides :
... 6x = - 3
Dividing by 6 on both sides :
... x = -1/2 = -0.5
Hence, the answer is -0.5
Hope my answer helps!
