PLEASE HELP!!!!

Marvin is a builder. A client gave Marvin this diagram of the dimensions of the triangular shelves that he would like Marvin to
build for his daughter's room.


Unfortunately, the client only sent him one of the angle measurements needed.
Which equation could be used to find the value of 2?

A. 180 - [180-2(70)] = x
B. 180 - 2(18) = x
C. 180 - 70 = x
D. 180 - 2(70) = x

The answer would be A. The triangle with the 70 seems to be isosceles and that means that two of the angles equal 70. 70+70=140. Subtract 140 from 180 to find the third angle because every triangle has a total of 180 degrees. Due to the fact that x and the 40 degrees are on the same line, they will equal 180 degrees. So, 180-40=140. X=140. I hope this helps
