hey, whats the answer and explanation for Sin 49 = Q/5 q means the unknown angle i just need formula or theory
Firstly, q is not an angle, it is the length of a side of a triangle.
\(\sin 49 = \dfrac{q}{5}\\ q=5\sin 49\)
No formula required.
5 sin 49 ≈ 3.773547901115
That means if an angle in a right-angled triangle is 49 degrees, and hypotenuse of the triangle = 5, the side opposite to the 49-degree angle is 3.773547901115.And this diagram:
