For 1, just solve 180-(65+45) and then for 2, subtract #1 and 45 from 180. Then just solve for #3 by using 180-(#2+20)
Answer:
b = 32
Step-by-step explanation:
If we are talking a² + b² = c² instead of looking for the hypotenuse we look for a leg and it doesnt matter where it is placed.. so for there forth you'll do
24² + b² = 40²
and then from there you square all the numbers so then you get
576 + b² = 1600
then subtract 576 from both sides so you are left with
b² = 1024
and finally square root it
b = 32
She will need 5 and a half hours. First step is to do 360-112.5 the pgs she read and her goal. then you'll get 247.5. To find how many hours you need to find the unit rate. so 247.5 divided by 45 is 5.5 hours.
hope this helped. can u mark me as the brainiest answer
