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
Answer:
C Hope this helps This may be wrong though
Step-by-step explanation:
Undefined has a 0 in the denominator and a slope of 0 has 0 as the numerator
What is IT? The question?
Answer:
see explanation
Step-by-step explanation:
Given
- 16 ← difference of 2 squares and factors in general as
a² - b² = (a - b)(a + b)
- 16
= (p² )² - 4²
= (p² - 4)(p² + 4) ← (p² - 4) is also a difference of squares
= (p - 2)(p + 2)(p² + 4)
