Answer: if my calculations are right X= -42x
Step-by-step explanation:
X =13 because it’s a 45-45-90 triangle and the sides take the 13square root of 2 and take the 2 out and you get 13. Sorry for the weird explanation, hope you understood.
Answer:
m∠ABC = 83°
Step-by-step explanation:
The angle ∠abc and ∠dbe are opposed by the vertex. By definition "<em>Two angles opposite the vertex are congruent or equal</em>"
So ∠abc = ∠dbe
Then, to solve this problem you must match both expressions and clear the variable x.

Now substitute x = 15 in the given expression for the angle ∠abc. (6x-7)
So, we have:
°
Finally, the angle is 83°
B. 84
The scale factor is 1/12 which means to get back to the actual height, you would multiply 7x12
