How can you find the surface area of a composite solid made up of a prisism?

If 90° < θ < 180° and cotθ = -1/3, then cscθ =

Cot(90° − x) = 1 the value of x that satisfies this equation is °. a. 60 b. 135 c. 225 d. 315

What happens to the area as the sliders are adjusted? what do you think the formula for the area of a triangle is divided by 2?
