Answer:

102

Step-by-step explanation:

it is an isosceles triangle as two sides are equal i.e 3.3 so angles opposite to equal sides are also equal so 39 plus 39 plus x = 180°

78 plus x =180

x=180-78

x=102°

Which property explains why these two expressions are equal?
ratelena [41]
Re-written, I believe the equation is:

(W+23)+5=W+(23+5)

With this, the parenthesis have nothing multiplying into it, so we can drop the parenthesis to get:

W+23+5=W+23+5
Which is the same thing.

So I'd assume it is the Associative property, because you are combining the like terms of 23 and 5.

Hope this helps!

4(y - 7) = 2y - 38
4y - 28  = 2y - 38
4y - 2y = -38 + 28
2y = -10
y = -5
