Answer:

145

Step-by-step explanation:

angles in a pentagon add up to equal 540

Hence, 110 + 90 + 80 + 115 + v = 540

( note that we just created an equation that we can use to solve for v )

We now solve for v using the equation created

110 + 90 + 80 + 115 + v = 540

step 1 combine like terms

110 + 90 + 80 + 115 = 395

we now have 395 + v = 540

step 2 subtract 395 from each side

540 - 395 = 145

395 - 395 cancels out

we're left with v = 145

Andreas93 [3]

Answer:

A) between 7:40 and 7:45

Step-by-step explanation:

Given,

The maximum time taken by her to walk to school = 15 minutes,

Since, the school starts on 8:00 AM,

Also, 15 minutes before 8:00 AM = 7:45 AM,

Thus, the maximum time at which she has to leave home = 7: 45 AM,

Hence, the reasonable estimate of the time she should leave home to get to school by 8:00 is between 7:40 and 7:45.

OPTION A would be correct.
