Answer:
25, 65, 65
Step-by-step explanation:
So first off, we should know that corresponding angles are congruent (equal). (3x-10) and (x+40) are corresponding angles.
So, because of this we set these two equal. 3x-10=x+40
Do the algebra. Subtract x on both sides and add 10 on both sides.
This gives you 2x = 50.
Divide by 2 on both sides.
This gives you x=25
Great. Now we know what x is, so x=25 Now we have to plug this in.
3(25) - 10 = 65
25+40 = 65
