So it is an isosceles triangle that means that the bottom two angles are equal...
so
40 = 5x
divide both sides by 5 and you get 8
now the triangle angles add up to 180
we make an equation out of it...
(2y + 20 ) + ( 5(8)) + 40 = 180
2y + 20 + 40 + 40 = 180
combine like terms
2y + 100 = 180
so subtract 100 from both sides
2y = 80
divide by 2 to isolate the variable
y = 40
You are correct!!! :)
Answer:
The answer is A.
Step-by-step explanation:
I'm very sorry if this is wrong but A would make the most sense. the formula y=mx+b. m is the slope, and b is the y-intercept so A is the most reasonable.

Answer:
2 on top and bottom of 4 5 is 3 on top and bottom and lastly 6 is 8 on top and bottom.
Step-by-step explanation:
all you have to do is divide the two bottom numbers on each problem and the answer to the problem will be the same on top and bottom
The answer is 17 , i just know that’s it
Answer: i dont this you can combine like terms for this question because none of these have the same variable or anything.
