slega [8]

Answer:

  • - 2 5/12

Step-by-step explanation:

  • −3 2/3 = x − 1 1/4
  • x = - 3 2/3 + 1 1/4
  • x = - 2 - 2/3 + 1/4
  • x = - 2 - 8/12 + 3/12
  • x = - 2 - 5/12
  • x = - 2 5/12

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
