Answer: Choice C
7 divided by cosec 50 degrees
=====================================
Explanation:
Abbreviations:
sec = secant
cot = cotangent
cosec = cosecant (csc is also a widely used abbreviation)
-----------------
Let the horizontal leg be x
This leg is opposite the angle 50 degrees. The hypotenuse is 7
Opposite = x
Hypotenuse = 7
We'll either use the sine rule or the cosecant (csc) rule
sine = opposite/hypotenuse
cosecant = hypotenuse/opposite
Since "sine" is nowhere to be found in the answer choices, we'll use the cosecant rule
-----------
cosecant = hypotenuse/opposite
csc(angle) = hypotenuse/opposite
csc(50) = 7/x
x*csc(50) = 7
x = 7/csc(50)
This is why the answer is choice C
30 degrees is the measure of y.
Answer:
it depends
Step-by-step explanation:
<em>Shino's formula will work for any prism</em>.
Angelo's formula will work for any prism whose base area can be found by ...
B = (1/2)ew
<em>Angelo can use this formula for a triangular prism</em>.
__
For a triangular prism, both may be correct.
For a prism of another shape, Shino is correct. (Angelo may also be correct, depending on the variable definitions.)
Answer:
the product of two numbers is 20; it is multiplication so that is why the end result is a product
