Convert 210° from degrees to radians. use the value of π found on a calculator, and round answers to four decimal places, as needed.

3.6651

Step-by-step explanation:

The formula to convert degrees to radians is given by :-

Given : Angle :

Then , the measure of angle in radians is given by :-

Using the value of , we get

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

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)
