Answer:

119

Step-by-step explanation:

By using exterior angle theorem, we know that 31+angle 1 =150. therefore angle 1=119. Exterior angle theorem is where an angle exterior of an angle in the triangle addus up to 180 degreees, we also know the angles in a triangle sum to 180 degrees. Both sides have a common angle. If we subract it from the equation, we get what is said above.

What is the slope of the line that is perpendicular to the line that goes through the two points (-8, 3) and (4, 27)?

Mademuasel [1]

Answer:

-1/2 or -0.5

negative half

Step-by-step explanation:

slope of regular line= (y1-y2) / (x1-x2)

(27-3) / (4 - -8)

24 / (4+8)

24 / 12 = 2

the slope of a perpendicular line is the negative reciprocal

the negative reciprocal of positive 2/1 (2 as a fraction) is:

negative half: -1/2 or -0.5

Serga [27]

Answer: x=100$

Step-by-step explanation:

use the slope formula

y=mx+b

plug in what you have

y=2400, m=22.50x, b=150

solve for x

2400=22.50x+150

subtract 150 from both sides

2250=22.50x

divide 22.50 x from both sides

x=100 people

don't forget your units :)
