40/1.4=28.57 i think this is right
Answer:
A = 50
Step-by-step explanation:
The sum of the angles of a triangle is 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 each side by 3
3x/3=90/3
x =30
We want to find A
A =2x-10
= 2*30 -10
=60-10
=50
Answer:
I would say A because the real answer is 23.477
