David had a tile that was an equilateral triangle. He concluded that each angle of the triangle measured 60°. Which of the following statements BEST justifies David’s conclusion? A. All acute angles have a measure of 60 degrees
b. every equilateral triangle is also an isosceles triangle
c. The sum of the measures of the angles in a triangle is 180 degrees, and the three angles are congruent
D. The measure of an exterior angle of a triangle is the sum of measures of its two remote interior angles

b. x- 48 =120

step-by-step explanation:

this is false ^.^ lol

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
