Super easy will give brainleist if done by 5: 30 pm. answer seriously or will report user. you < 3

I know this is a bit late but it is 6 and 12

Step-by-step explanation:

if we use the formula b1 + b2 x h/ 2, u would do inverse operations. you multiply 2 on each side so that 72 would equal b1+b2xh and divide height on each side to get 18 is b1 + b2. if b1 is 2 times, it would be 2x + x is 3x and divide 3 on each side would give you 6 for x. If 6 is x, one side would be 6 and the other would be 12

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
