The picture below shows a right-triangle-shaped charging stand for a gaming system: The side face of a charging stand is a right triangle labeled ABC. The measure of angle ACB is 90 degrees, and the measure of angle ABC is 50 degrees. Side BC measures 3 inches. Which expression shows the height, AC, of the charging stand? 3 over cos 50 degrees 3(tan 50°) 3 over tan 50 degrees 3(cos 50°)

step-by-step explanation:

the answer is d

step-by-step explanation:

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
