Estimate the time Juanita will arrive at her aunt's home 320 miles away if she leaves at 9:00 a. m., drives about 60 miles per hour, and stops for a 40 minute break halfway.
A 12:00 p. m.
B. 1:00 p. m.
c. 2:00 p. m.
D. 3:00 p. m.
E. 4:00 p. m.

the answer is 5/14.

hope this .

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.

h is the x-coordinate of the vertex

step-by-step explanation:

we have

in this function

the point represent the vertex of the function

so

h is the x-coordinate of the vertex

k is the y-coordinate of the vertex
