Answer:
the answer is the 3rd one
Answer:
Csc(0)
Step-by-step explanation:
in trigonometry, the basic functions are Sine , Cosine and Tangent. Other functions such as Cotangent, Secant and Co secant are derivatives of these 3.
We know that
Csc Ф = 1/Sin Ф
Cot Ф = 1/tan Ф = cos Ф/ sin Ф
hence cos(0) csc(0)/sin(0)cot(0)
= cos Ф * 1/sin Ф ÷ sin Ф *cos Ф / sin Ф
= cos Ф/sin Ф * 1/ cos Ф
= 1/ sin Ф
= Csc Ф
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°.
