Answer:
QR = 4.6 ft
Step-by-step explanation:
By applying tangent rule in the given triangle PQR,
tan(62°) = 
= 
QR = 
QR = 4.573
QR ≈ 4.6 ft
Answer:
1. 2x can be seen as +2x therefore when you put it as +2x-5x the answer will be - 3x
2. +3a+2a also equals +5a
3. - 5 is left alone and there is no other similar expression
Put them together the answer becomes
-3x+5a-5
It doesn't have to be the same order of format but the numbers must be as such
We need x and y
Opposite sides of a parallelogram are equal
And
Hence
- QR=TS=5x-1=5(2)-1=9
- RS=QT=y+8=5+8=13
#3
Segment QT is 4
so
Another way
So
scale factor:-
Find y
About $17.05,
Since 89/100= 1% of the total bill= 0.89
0.89*15= the total tip= 13.35
Add the total bill and the tip together would be $102.35,
And then you divide that between the 5 of your friends and you, so
102.35/6 which would equal to $17.0583 (3 repeating) for each person.
