19,3/4 = 79/4
15,3/4 = 63/4
Perimeter = 79/4+79/4+63/4+63/4 = 284/4 = 71feet
22,1/2 = 45/2 X 4 = 90
90-71= 19 feet
Let me know if you need more of an explanation, but the answer in 19 feet (option 4)
Answer:
50°
<u>In</u><u> </u><u>order</u><u> </u><u>to</u><u> </u><u>determine</u><u> </u><u>the</u><u> </u><u>unknown</u><u> </u><u>angle</u><u>,</u><u> </u><u>be</u><u> </u><u>sure</u><u> </u><u>to</u><u> </u><u>use</u><u> </u><u>the</u><u> </u><u>total</u><u> </u><u>sum</u><u> </u><u>of</u><u> </u><u>1</u><u>8</u><u>0</u><u>°</u><u> </u>
120° - 180°= <em><u>60°</u> </em>( this give you the red side inside the triangle)
Then you simple add the two number inside the triangle
<em><u>6</u><u>0</u><u>°</u></em> + 70° = <em><u>130°</u></em>( then you use this to find the missing corner by subtracting from 180°)
180°- <u>1</u><u>3</u><u>0</u><u>°</u> = 50° this is your missing angle X"
To prove it simple add all the 3 angles inside the triangle add up to 180°
<u>6</u><u>0</u><u>°</u> + <u>7</u><u>0</u><u>°</u> + <u>5</u><u>0</u><u>°</u> = <u>1</u><u>8</u><u>0</u><u>°</u>
<u>X</u><u> </u><u>=</u><u> </u><u>5</u><u>0</u><u>°</u>

Step-by-step explanation:
13!=13×12×11×10×9×8×7×6×5×4×3×2×1
=6,227,020,800
It's a 2/1 slope so you would make your Rise/Run chart and rise 2 the run right 1
