Answer:

A. 24

Step-by-step explanation:

Angles in a triangle add up to equal 180

Thus, 66 + 90 + x = 180

66 + 90 = 156

156 + x = 180

180 - 156 = 24

Hence, x = 24

Note: There is a right angle indicated by the square inside of the triangle. A right angle has a measure of 90 degrees. So Just in case you were wondering that's where the 90 cam from

<h3>Answer:</h3>

Rectangle:

<em>[</em><em>L</em><em>e</em><em>n</em><em>g</em><em>t</em><em>h</em><em> </em><em>x</em><em> </em><em>B</em><em>r</em><em>e</em><em>a</em><em>d</em><em>t</em><em>h</em><em>]</em>

5 + 3 = 8inch

8 x 2.5 = 20inch^2

Right Triangle:

<em>[</em><em>1</em><em>/</em><em>2</em><em> </em><em>x</em><em> </em><em>B</em><em>a</em><em>s</em><em>e</em><em> </em><em>x</em><em> </em><em>H</em><em>e</em><em>i</em><em>g</em><em>h</em><em>t</em><em>]</em>

1/2 x 5 x 2 = 1/2 x 10

= 5inch^2

Left Triangle:

<em>[</em><em>1</em><em>/</em><em>2</em><em> </em><em>x</em><em> </em><em>B</em><em>a</em><em>s</em><em>e</em><em> </em><em>x</em><em> </em><em>H</em><em>e</em><em>i</em><em>g</em><em>h</em><em>t</em><em>]</em>

1/2 x 3 x 2 = 1/2 x 6

= 3inch^2

20 + 5 + 3 = <u>2</u><u>8</u><u>i</u><u>n</u><u>c</u><u>h</u><u>^</u><u>2</u>
