Answer:
Hi,
Step-by-step explanation:
PR²=PQ²+QR²-2*PQ*QR*cos(51°)
=15²+12²-2*15*12*cos(51°)
=142,444659....
PR=11.9350...
PQ²=QR²+PR²-2*QR*PR*cos(R)
cos(R)=(12²+142.444...-15²)/(2*12*11.9350...)=0,21451112....
angle R=77,61315...°≈77.6°
angle P=180°-51°-77.6°≈51,4°

Step-by-step explanation:
just look at the line.
the distance between 2 whole numbers is split into 1/2, then each 1/2 again into 1/2 = 1/4, and then every 1/4 again into 1/2 = 1/8. so, in total, we are dealing with 8 segments of 1/8 length.
now we count : we have a full 1, and then on the way to 2 we get only 5 units of 1/8 = 5/8.
so, in total the number is
1 5/8
Step-by-step explanation:
1 quarter + 1 nickel = 30c
1 quarter + 1 penny = 26c
1 nickel + 1 penny = 11c
1 quarter + 1 nickel + 1 penny = 31c
There are 4 different sums of money.
