Akite has angle measures of 7x, 65, 85, and 105. find the value of x. what are the measures of the angles that are congruent?

Step-by-step explanation:

A kite is a quadrilateral, so the sum of its angle measures is 360°.

  7x + 65 + 85 + 105 = 360

  7x = 105 . . . . . . . . . . . . . . . . . subtract 255. This answers the second part of the question: the missing angle is 105°, so is congruent to the 105° angle given.

  105/7 = x = 15 . . . . . . . . . . . . divide by the coefficient of x

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s
