Answer:
<h2>398.88hours</h2>
Step-by-step explanation:
Note: If Ava decides to reduce the time she does each activity by 16minute I believe it should be
1. Ava spends 45min per day studying
reduce this amount be 16min we have=45-16=29min
in a year she will spend 365*29= 10585min
2. She also practices the piano for an average of 20 minutes per day
reduce this amount be 16min we have=20-16=4min
in a year she will spend 365*14= 5110min
3. She practices soccer 1.5 hours three times a week.
in minutes 1.5hours is 90min three times a week
in a day 90*3/7= 270/7=38.57
reduce this amount be 16min we have=38.57-16=22.57min
in a year she will spend 365*22.57= 8238.05min
in total for the year she spends studying and practicing
=10585+ 5110+8238.05
=23933.05min to hours =23933.05/60
=398.88hours
EXPLANATION
Let's see the facts:
------------------------First triangle ----------------------------
First side measure =3
Second side measure = 4
Included angle measure = 62
----------------------Second triangle ------------------------
First side measure = 27
Second side measure= 36
Included angle measure = 62
We have two included and congruent angles because 62=62.
Let's make a representation:
Now, in order to conclude if both triangles are similar we need to prove that the relationship or ratios between the sides is the same, and then, by the S-A-S Postulates, we could infer that both triangles are similar.
First side relationship: 3/27 = 1/9
Second side relationship: 4/36 = 1/9
1/9 = 1/9
As First side relationship = Second side relationship, then the relationship is the same and by SAS Postulate, the triangles are similar.
Are the triangles similar? Yes, by SAS postulate.
we know that
if JKLM is a rectangle
then
diagonals
MK=JL
so
MK=2*MN------> MK=2*25 ft------> MK=50 ft
JL=MK----> JL=50 ft
therefore
the answer is
JL is 50 ft
