Can someone answer with steps and explanation? Thanks.

Step-by-step explanation:

Since ΔABC is mapped onto ΔDEF, we can write that:

By CPCTC:

And since ΔABC is isosceles with Vertex C:

We are given that:

Hence:

We are also given that:

The interior angles of a triangle must sum to 180°. Thus:

Substitute:

Simplify:

Isolate the equation:

Factor:

Zero Product Property:

Solve for each case:

Testing the solutions, we can see that both yields C = 112°.

Hence, our solutions are:

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.
