Answer:
x = 70°
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
120° is an external angle of the triangle, thus
x + 50 = 120 ( subtract 50 from both sides )
x = 70

Answer:
Step-by-step explanation:
Slope of line through the three points is -3.
Slope of any perpendicular through the line is ⅓.
(0,1) is one of the points on the line, so the y-intercept is 1.
Slope-intercept equation for line of slope ⅓ and y-intercept 1:
y = ⅓x+1
First arrange numbers
14,15,15,17,19,20,21,23,24
19 is median
15+15/2=15 is first quartile
