Answer:
This is simple. The answer is 60 for the first, and the second one I believe is 85
Step-by-step explanation:
Since we are dealing with quadrilaterals, we know that all the inside angles add up to 360. In your isosceles trap. the top two angles are the same, and the bottom two are the same. So, we can do 120*2=240 for the top angles, and then subtract that from 360. 360-240=120. 120/2=60

Answer:
a. Ryan 70mph. Janelle 65mph.
b. 4 hours and 48 minutes.
Step-by-step explanation:
a. Ryan 245/3.5=70 mph. Janelle 260/4=65 mph.
b. If Janelle drives 575 miles with the speed of 65 mph, in total it would take her 575/65=8.8 hours, which is 4.8 hours more than 4 hours. (0.8 hours is 48 minutes).
