Draw and label a standard Oblique Triangle, as we’ve done in our previous lessons.
Determine the given congruence, either SAS or SSS, and pick the equation that helps you solve for either a missing side or angle.
Plug into your chosen equation and solve.
The "Law of Cosines" can be used to calculate one side of a triangle when the angle opposite and the other two sides are known. The "Law of Cosines" can be expressed as c2 = a2 + b2 - 2 a b cos C (1)
The cosine rule is an extension of this mathematic principal that makes it effective for non-right triangles and states that in regard to a certain angle, the square of the side of the triangle opposite that angle is equal to the squares of the other two sides added together, minus two times both..
An = -2n(n + 3)
a(15) = -2(15)(15 + 3) = -30(18) = -540
Idk u might need to use a calculator trust me
Answer:
<u><em></em></u><u><em></em></u>
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the trigonometric function
we know that sin²∝ + cos²∝ = 1
⇒ sin²∝ = 1- cos²∝
Now we have to simplify the given trigonometric function
=
=
<u><em>Step(ii)</em></u>
we know that cosec∝ = 1/ sin∝
=
After cancellation sine function, we get
=
<u><em>Final answer:-</em></u>
