Please help how do you solve this?

Answer:

A, 120 degrees

Step-by-step explanation:

=============================================================

Explanation:

Triangle ABC is equilateral, so all three sides are the same length. This means the three angles are also the same measure. Call each interior angle x.

The three angles add to 180, so x+x+x = 180 solves to x = 60. Each interior angle is 60 degrees.

Angle DAC is an exterior angle of measure 180-x = 180-60 = 120 degrees

------------

Or another method you could use is the fact that all exterior angles of any polygon add to 360.

Since we have n = 3 sides, this means each exterior angle of an equilateral triangle is 360/n = 360/3 = 120 degrees

We consider this a regular polygon because all sides are the same length and all angles are the same measure. So the formula for the exterior angle measure 360/n would apply to any regular polygon and not just triangles.

Emily, Zeke, Harry, and Brook each conducted surveys on the number of books people have in their homes. Then, each student determined the accuracy of the following statement.
All measures of central tendency must appear as a number in the set of data collected.
Which student’s statement is CORRECT?
A.
Zeke says this is never true because all the measures of central tendency are never numbers in the set of data.

B.
Emily says this is always true because all the measures of central tendency also have to be numbers in the set of data.

C.
Harry says this is sometimes true because the mean and median may or may not be in the set of data, but the mode is always in the set of data.

D.
Brook says this is sometimes true because the mean and mode may or may not be in the set of data, but the median is always in the set of data.

Why do equivalent ratios form a straight line when graphed?

The vertical distance between points is constant, and the horizontal distance between points increases with each point.

The ratio of the change in y-values to the change in x-values is equivalent for any two points in a graph of equivalent ratios.

The horizontal distance between points is constant, and the vertical distance between points increases with each point.

The y-values of equivalent ratios increase at a constant rate, and the x-values decrease at a constant rate.

Eliza intends to buy a new vehicle. She wishes to estimate the mean fuel efficiency (in miles per gallon) of all family sized SUV's currently available on the market.
