Answer:
perimeter ≈ 12.4 units
Step-by-step explanation:
The side adjacent to the angle is given. The relationships useful for the other two sides are ...
Tan = Opposite/Adjacent
Cos = Adjacent/Hypotenuse
From these, we have ...
opposite = 5·tan(22°) ≈ 2.02
hypotenuse = 5/cos(22°) ≈ 5.39
Then the perimeter is ...
P = a + b + c = 2.02 + 5 + 5.39 = 12.41
The perimeter of ∆ABC is about 12.4 units.

<h2>
![5 - \frac{3}{4} x = 8](https://tex.z-dn.net/?f=5%20-%20%20%5Cfrac%7B3%7D%7B4%7D%20x%20%3D%208)
</h2>
Step-by-step explanation:
<em><u>Let</u></em><em><u>,</u></em>
The number be = x
<em><u>Given</u></em><em><u>,</u></em><em><u> </u></em>
Three - fourth of the number =
![\frac{3}{4} x](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B4%7D%20x)
Then subtracted from 5 =
![5 - \frac{3}{4} x](https://tex.z-dn.net/?f=5%20-%20%20%5Cfrac%7B3%7D%7B4%7D%20x%20)
Result would be = 8
<em><u>Hence</u></em><em><u>,</u></em>
Required equation
