Find the value of x, use image

x = 168

Step-by-step explanation:

A hexagon's total interior angles sums up to be 720, so what you have to do is just subtract.

x = 720-(84+128+150+103+87)

x = 168

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
