Alex is writing statements to prove that the sum of the measures of interior angles of triangle pqr is equal to 180°. line m is parallel to line n. line n is parallel to line m. triangle pqr has vertex p on line n and vertices q and r on line m. angle qpr is 80 degrees. segment pq makes 40 degrees angle with line n and segment pr makes 60 degrees angle with line n. which is a true statement he could write? angle prq measures 40°. angle pqr measures 60°. angle prq measures 80°. angle pqr measures 40°.

the slope of the first function is -3. (3/1)

the slope of the second function is 1. (13-10/6-3).

since |-3| is greater than |1|, the function with the steepest slope is the first.

ummm seems that u didnt post the attachement !

step-by-step explanation:

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
