x = 6
Step-by-step explanation:
Right Triangle
We are given a right triangle whose shortest side has a length of 3 units. This side must be opposite to the smallest acute angle of 30°.
The triangle is shown in the figure attached.
The tangent ratio relates the opposite side with the adjacent side. The formula can be applied to the angle of 30° as follows:
Solving for y:
Since:
Now applying the sine to find the hypotenuse x:
Solving for x:
Since:
x = 6

example you can find the perimeter by addig all of its respective sides as such: (12+x)+(12+x)+(7+y)+(7+y). adding like terms will result in 2x+2y+38 if you chose xy+7x+12y+84, you multiplied the two sides to find the area. if you chose x+y+19
