If the angle of elevation to the top of a 100 feet tall building is 47° from point C, how many feet is point C from the base, A?

answer is (b.

164 ft2)

a base  

18

b base  

7

h height  

8

h is the x-coordinate of the vertex

step-by-step explanation:

we have

in this function

the point represent the vertex of the function

so

h is the x-coordinate of the vertex

k is the y-coordinate of the vertex

d .tv

step-by-step explanation:

the side tv is included in both triangles.   this means it corresponds to itself in the transformation.

this is justified by using the reflexive property, which states that anything is congruent to itself.
