Answer:
csc (- 30)° = - 2
Step-by-step explanation:
Using the trigonometric relationship
csc x =
and the exact value sin30° = 
sin(- 30)° = - sin30° = -
, thus
csc (- 30)° =
= - 2
For volume of a prism, the general rule is multiply the area of the base by the area of the height. For example, for a triangular prism, the volume would be (1/2)b*h*a if you set a = height of the prism and h = height of the triangle from the formula (1/2)bh, which is the area of a triangle.
Answer:
the answer is each piece of trim is 43 cm long
185-13 = 172
172 divided by 4 pieces came out to 43 cm
(I don't know the equation part)
