The true statement about right-angle triangle ABC is that: A. sin(A) = cos(C) and cos(A) = sin(C).
<h3>How to apply basic trigonometry?</h3>
In order to determine the angles, we would apply basic trigonometry. From the diagram of the right-angled triangle shown below, we can deduce the following parameters:
By applying the basic trigonometry functions, we have:
sin(A) = Opp/Hyp = a/c.
sin(C) = Opp/Hyp = c/b.
cos(A) = Adj/Hyp = c/b.
cos(C) = Adj/Hyp = a/c.
From the above, we can logically deduce that sin(A) is equal to cos(C) and cos(A) is equal to sin(C).

Answer:
1) B
Step-by-step explanation:
1)
The formula for the volume of a prism is h * l * w
So, if we do that we get 25/18
2) B
Lets say we talk the top surface, there are 30 cubes on that surface and we want to find the volume of one cube so we are going to divide by 50. we take the measurements which are 5/6 and 1 for the top surface and we multiply. We get an answer of 5/6 now we divide by 30
So...
5/6 * 1/30 (We switched the numbers around because we are dividing.)
5/6 * 1/30 = 5/180 now we can simplify this to 1/36.
5 and 180 are a factor of 5
Hope this helps
To find the total measure of the angles in a polygon, the formula is 180(n-2) n being the number of sides in the polygon.
So the correct answer is B) 180(14-2)
