A = B1 + B2/2 x H

First add the bases.
Base 1 (top) . 4 + 15 + 6 = 25.
Base 2(bottom) 15.
25 + 15 =40.

Next divide by 2
40 ÷ 2 = 20.

Last. Multiply by height.
The height of this trapezoid is 7in because the height must be perpendicular to the base. (NOT the SLANTED LINE)
20 x 7 = 140.
Don't forget the Units of measure!
Because this is area 140 in. = 140²

Answer:

${f}^{ - 1} (x) = 9x + 18$

Step-by-step explanation:

$f(x) = \frac{1}{9}x - 2$

$y = \frac{1}{9} x - 2$

$x = \frac{1}{9}y - 2$

$x + 2 = \frac{1}{9}y$

$9x + 18 = y$

${f}^{ - 1} (x) = 9x + 18$

Given: AB || DE , AD bisects BE. Prove: ABC = DEC using the ASA postulate.

Answer:

As per ASA postulate, the two triangles are congruent.

Step-by-step explanation:

We are given two triangles:

$\triangle ABC$ and $\triangle DEC$ .

AD bisects BE.

AB || DE.

Let us have a look at two properties.

1. When two lines are parallel and a line intersects both of them, then alternate angles are equal.

i.e. AB || ED and $\angle B$ and $\angle E$ are alternate angles $\Rightarrow$ $\angle B = \angle E$ .

2. When two lines are cutting each other, angles formed at the crossing of two, are known as Vertically opposite angles and they are are equal.

$\Rightarrow \angle ACB = \angle DCE$
