Jane's percentile score is 98.
She has scored higher than 49 out of 50 students taking the test (98%).
Triangle PDQ has:
Side "p" is opposite Angle P
Side "d" is opposite Angle D = 45º + 23º = 68º
Side "q" is opposite Angle Q
Use the Law of Cosines:
d² = p² + q² − 2 • p • q • cos(D)
d² = (4.24)² + (4.24)² − 2 • (4.24) • (4.24) • cos(68º)
d² = 2(4.24)² − 2(4.24)² • cos(68º)
d² = 2(4.24)² • [ 1 – cos(68º) ]
<span> d = 4.74 ft

Answer: BC=18
DG=6
Step-by-step explanation: well we have to use similarity. and that means setting up proportions so... 15/10 = BC/12 10BC=180, BC=18
9/18=DG/12 (we put 18 because it equals BC)
hope this helped!!
Answer:
45.88 seconds

So the time it took the choir to sing the third time was 45.88 seconds.
<span>(5, 0) and (5, -2) are the two points that are on the line x=5. This is some basic math.
Hope it helps :)</span>
