Area of the rectangle: 112

Step-by-step explanation:

Picture is missing: find it in attachment.

The area of a triangle is given by

A=\frac{1}{2}bh

where

b is the length of the base

h is the height

For triangle ABE, we know that

A = 40 (area)

h = 8 (height)

So we can find the length of the base AE:

AE=b=\frac{2A}{h}=\frac{2(40)}{8}=10

Now we observe that the base of the rectangle, AD, is the sum of AE and DE, therefore:

AD=AE+DE=10+4=14

We also know the height of the rectangle AB is 8, and that the area of a rectangle is

A=bh

where b is the base and h the height. Therefore, the area of this rectangle is

A=bh=(AD)(AB)=(14)(8)=112

What is the answer to 3x+2-x=11x-9
Elenna [48]
3x+2−x=11x−9
Step 1: Simplify both sides of the equation.
3x+2−x=11x−93x+2+−x=11x+−9(3x+−)(2)=11x−9
(Combine Like Terms)
2x+2=11x−92x+2=11x−9

Step 2: Subtract 11x from both sides.
2x+2−11x=11x−9−11x−9x+2=−9

Step 3: Subtract 2 from both sides.
−9x+2−2=−9−2−9x=−11

Step 4: Divide both sides by -9.
−9x−9=−11−9x=119
ANSWER: 11/9

Gwar [14]

Answer:

∠XBA=43°

Step-by-step explanation:

we know that

If ray BA bisect angle ∠XBY

then

∠XBA=∠XBY/2

we have

∠XBY=86°

substitute

∠XBA=86°/2=43°
