0.5(30) = 0.25(x). Divide each side by 0.25.
60 = x.
1/4 of 60 = 1/2 of 30
Answer:
The length of the rhombus is =
Step-by-step explanation:
It is given that the Rhombus ADEF is inscribed into a triangle ABC so that they share angle A and the vertex E lies on the side BC.Then,
AE is the angle bisector of ∠A, so divides the sides of the triangle into a proportion:
⇒
⇒
Now, ΔDBE is similar to ΔABC, then
DE=
=
=
Thus, the length of the rhombus is =
A=Area
A=3.14 x 10²=20
A=3.14 x 20 = 62.8
A=62.8
