208/16 = 13 yards per part
13-4 = 9 yards of unpainted strip per strip
9*16 = 144 of unpainted strips
Answer:
Step-by-step explanation:
There are 180 degrees in a triangle. With that information we can make the equation: 180=(47+85)+x.
When you solve it becomes:
180=132+x --> x=48 degrees
Hope that helped!
The law of cosines states that, if
is the angle between sides b and c,

So, plugging our values, we have

This is equal to

The choices are found elsewhere and the figures would be:
a. rectangleb. trianglec. squared. trapezoid
From the choices, the answer would be option B. A triangle figure would be the cross section when <span>a rectangular pyramid that has been intersected by a plane perpendicular to its base and through</span>its vertex.
