Answer:
m∠YKZ = 90°
Step-by-step explanation:
PRYZ is a rhombus.
Property of a rhombus:
The diagonals of a rhombus are always perpendicular.
This means lines PY and RZ are perpendicular.
By definition of perpendicular lines, they intersect at right angle. Right angle has the measure of 90°, hence
m∠YKZ = 90°
Average rate of change = (f(29) - f(15))/(29 - 15) = (87 - 45)/14 = 42/14 = 3m/s^2
I think 6x3=18
So, the answer is 18
