What is the measure of ZB of the pentagon?

111°

Step-by-step explanation:

The sun of interior angles in a pentagon is 540° so to find the measure of B we gotta add all given measure up then subtract it from 540

150° + 98° + 89° + 92° + B = 540° ➡ B = 111°

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.
