I'm having trouble with this problem. I need to find the x number of employees. "Kiara went to the restaurant and waited 3.5 minutes. How many employees were working at the registers? Round to the nearest whole number if necessary. Using the equation y = -70x + 300, where y is the total amount of time waited in seconds and x is the number of employees working registers."

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

step-by-step explanation:

intersecting chords are just lines that intersect. so a line is equal to 180 degrees, so when it is intersected by another chord, then it create supplementary angles, and because the lines cross, vertical angels are also formed.
