Answer:
Step-by-step explanation:
Since this is not a right triangle, we will use the Law of Sines. For us that looks like this:
and cross multiply to get
4sin55 = 3.5sinx and solve for sinx:
so
sinx = .9361737 Use the 2nd button on your calculator and the sin button to find that the angle
x = 69.4°. Not sure how you need it rounded. It's actually 69.4186°
The formula for the volume of a prism is V=Bh , where B is the base area and h is the height. Then after multiplying the base and height get that answer and put the units in whatever it says too. Like if base is 7 inches and height is 12 inches you would put 84 in squared( 84 in ^2). Cubic units is like 160 in ^3( 160 inches cubed)
It is 60 since it is clearly not 30 and not 90 either. 120 and 150 are irrelevant.
