There is no given equation, so it is impossible to figure this out. I apologize.
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°
Answer:
you can solve the equations using the roots formula and then find the values from the range that they've given you
then you just have to plot the graph and connect the dots to make a line
Convert 4ft. and 5ft. to inches (48 and 60). then multiply your length by your width to find the area of the tile. 48*60=2,880sq in.
