Given two similar triangles
So, the corresponding angles are congruent, and the corresponding sides are proportional
As shown:
m∠ Y = 35, m∠ X = 90
So, m∠ W = 90 - 35 = 55
And the triangle XYW is similar to the triangle ECD
So,
What the sum of 57.03 + 2.08

Answer:
True: B, C and D
Step-by-step explanation:
The graph of the function is shown in the attached diagram.
The vertex of the parabola (parabola is the graph of the function f(x)) is at (-3,-16), because
So, option A is false and option B is true.
As you can see from the graph, the function is increasing for all x>-3, thus option C is true.
The graph is positive for x<-7 and x>1 and negative for -7<x<1, so option D is true and option E is false.
