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:
It is the second answer!
Step-by-step explanation:
Answer:
~96.6
Step-by-step explanation:
120/124 is 30/31 or 60/62 or 96.6/99.82
Answer:
The gcf is 6.
so
we can divide by 6 on both sides to create
6(3y + 6)
