Answer:
16.2
Step-by-step explanation:
The angle internal to the triangle at B is the supplement of the one shown, so is 65°. That is equal to the angle internal to the triangle at D. Since the vertical angles at C are congruent, the two triangles are similar by the AA theorem.
Corresponding sides of similar triangles are proportional, so we can write the proportion shown in the attachment:
BC/FC = DC/AC
BC = FC(DC/AC) = 21.6(7.2/9.6)
BC = 16.2 . . . . matches the first choice
Answer:
h = 66
Step-by-step explanation:
We are given the equation of one variable h and we have to solve the equation for h.
The equation is given by
⇒ {Adding 17 to both sides}
⇒
⇒ h = 22 × 3 {Since we know that if then we can write
}
⇒ h = 66 (Answer)
