the area of a trapezoid is 36 square inches. The height is 4 inches and one bases twice the length of the other base. What are t

vlada-n [284]

The formula for this is $A= \frac{1}{2} ( b_{1} + b_{2} )h$ . Filling in accordingly, $36= \frac{1}{2}(x+2x)(4)$ . This simplifies to $36= \frac{1}{2}(3x)(4)$ and 36=6x. Therefore, x = 6 so the bases are 6 and 12.

8. In the figure, ADC is a straight line.

dlinn [17]

Answer:

a). ΔABC ~ ΔBDC

b). m(BD) = 6 units

Step-by-step explanation:

If ΔABC ~ ΔBDC,

a). Ratio of the corresponding sides of both the triangles will be equal.

$\frac{AB}{BD}=\frac{BC}{DC}=\frac{AC}{BC}$

$\frac{BC}{DC}=\frac{AC}{BC}$

$\frac{12}{9}=\frac{7+9}{12}$

$\frac{4}{3}=\frac{4}{3}$

Since Ratio of the corresponding sides are same, therefore, both the triangles are similar.

b). $\frac{AB}{BD}=\frac{BC}{DC}$

$\frac{8}{BD}=\frac{12}{9}$

BD = $\frac{9\times 8}{12}$

BD = 6
