In this case, we must use trigonometry to find the value of x:

$tan(\alpha )=\frac{side-opposite-angle}{side-beside-angle} \\tan(70) = \frac{x}{3} \\3*tan(70) = x\\x = 3*tan(70)\\x = 8.24$

Thus the value of x rounded to the nearest tenth is 8.2

Hope that helps!

Answer:

145 yards squared

Step-by-step explanation:

So the area of the base is area of a square with side length of 5 yards $5*5=25$

The area of one triangular face base times height divided by two and then simply multiplied by 4 because there are 4 triangular faces.

$(\frac{5*12}{2} )*4 = 120$

So the total surface area is $25+120=145$ yards squared

(12/52)*(11/51)=132/2652=11/221
