The question is not complete, a complete question is attached.
Solution:
A triangle is a polygon with three sides and three angles. Types of triangles are right angled, obtuse, acute, scalene, isosceles, equilateral triangle.
Trigonometric identities are used to show the relationship between the sides and the angles in a right angled triangle. Below are some trigonometric identities:
sin(θ) = opposite / hypotenuse; cos(θ) = adjacent / hypotenuse; tan(θ) = opposite / adjacent
The hypotenuse is the longest side in the triangle.
From the image attached:
sin(α) = opposite side / hypotenuse side
sin(α) = 7 / 25
