14-3=11 So she needed to cut of 11 yards of fabric.
Answer:
m∠B ≈ 51.5°
Step-by-step explanation:
A triangle solver can find this answer simply by entering the data. If you do this "by hand," you need to first find length BC using the Law of Cosines. Then angle B can be found using the Law of Sines.
<h3>Length BC</h3>
The Law of Cosines tells us ...
a² = b² +c² -2bc·cos(A)
a² = 21² +13² -2(21)(13)cos(91°) ≈ 619.529
a ≈ 24.8903
<h3>Angle B</h3>
The Law of Sines tells us ...
sin(B)/b = sin(A)/a
B = arcsin(sin(A)×b/a) = arcsin(sin(91°)×21/24.8903)
B ≈ 57.519°
The measure of angle B is about 57.5°.
If there is 51 liters currently in the pool, and it is rounded to the nearest hundred; the answer would be 100 liters.
Answer:
500 childrens tickets
600 adults tickets
Step-by-step explanation:
$11.00 * 500 = 5,500
$36.00 * 600 = 21,600
21,600 + 500 = 27,100 tickets sold
