Step-by-step explanation:

<h2>a) <em><u>x</u></em><em><u> </u></em><em><u>+</u></em><em><u> </u></em><em><u>14</u></em><em><u> </u></em><em><u>+</u></em><em><u> </u></em><em><u>3x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>90</u></em></h2><h2><em><u>b</u></em><em><u>)</u></em><em><u> </u></em><em><u><</u></em><em><u>1</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>33</u></em><em><u>°</u></em></h2><h2><em><u><</u></em><em><u>2</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>57</u></em><em><u>°</u></em></h2>

<em>As</em><em>,</em>

x + 14 + 3x = 90 <em>[</em><em>Complementary</em><em> </em><em>Angles</em><em>]</em>

=> 4x = 90 - 14

=> 4x = 76

=  > x =  \frac{76}{4}

=> x = 19

<em><u>Hence</u></em><em><u>,</u></em>

<em><u><</u></em><em><u>1</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>x</u></em><em><u> </u></em><em><u>+</u></em><em><u> </u></em><em><u>14</u></em><em><u>°</u></em>

Khan academy is just ‍♂️ I WANNA CRYY
Lina20 [59]

Answer:

h = 14 units

Step-by-step explanation:

Given:

Area of parallelogram = 84 units²

base length = 6

height = h

Required:

The missing height

SOLUTION:

Area of parallelogram = base × height

Plug in the values into the equation

Thus:

84 = 6 × h

84 = 6h

Divide both sides by 6

84/6 = 6h/6

14 = h

h = 14 units
