Which of the following trigonometric expressions is equivalent to csc(-112°)? csc(68°) cot(112°) -csc(68°) csc(112°)

Step-by-step explanation:

To find:

Solution:

Trigonometric expression is an expression consisting of trigonometric ratios like

Trigonometric ratios refers to the relation between the sides of right angled triangle and it's angles.

We know that angle lies in the fourth quadrant in which is negative

So,

We can write

We know that angle lies in second quadrant in which is positive

Therefore, we get

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

both triangles are similar because 2 is just smaller than the big one 1 is similar because they are facing different way's but are similar to each other
