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:
f(x) = (x - 4)^2
Step-by-step explanation:
When plotted upon a graph, the function passes through the line. You can find the vertex by using the formula: f(x) = a(x - h)^2 + k
h = 4, meaning the vertex is (4, 0)
Hope this helps!
1 foot = 12 inches
The 4 ribbons is 8 feet because each ribbon is 2 feet each
You would multiply the 8 ft by 12 to convert the feet to inches
8 ft. x 12in = 96in.
Then add the remaining ribbon
96 + 10= 106 inches of ribbon
It could be 5(8*7)4* it could be ok
Answer:
The answer to your question is: hypotenuse = 53 m
Step-by-step explanation:
Data
Opposite leg = 28
