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°
Answer:
880
Step-by-step explanation:
20 x 10% = 2
20 + 2 = 22
22 x 40 = 880
The zeros of a function are the x-values which make y=0. When we look at them on a graph, it's the places where the graph intersects the x-axis.
