Answer:

The area of the Triangle is 1/2 the area of the Rectangle

The answer is D.

Step-by-step explanation:

Ignore the area of the rectangle for the moment, just so you can get the answer.

Area Triangle = 1/2 * b * h

Area Triangle = 1/2 * 8 * 4

Area Triangle = 1/2 32

Area Triangle = 16 square feet.

The area of the rectangle = L * W

L = 8

W = 4

Area of the rectangle = 8*4 = 32

I need this problem solved real quick
PIT_PIT [208]

<u>Let's take this problem step-by-step</u>:

<u>The ;unlabeled angle' adjacent to the 'outside angle of measure 78°'</u>

  ⇒ is on a straight line

     ⇒ sum of angle measure = 180 degrees

       unlabeled_.angle+78 = 180\\unlabeled_.angle = 102

<u>Now we know:</u>

 ⇒ sum of all angles in a triangle ⇒ 180°

<u>Let's put that in equation form and solve:</u>

  x + 102 + 57=180\\x + 159=180\\x = 21

<u>Answer: 21°</u>

<u></u>

Hope that helps!
