Kindly check explanation
Step-by-step explanation:
A right - angled triangle is one which has one of its angles being 90°. Once we have a right angled triangle, the rule of Pythagoras can be applied in other to solve problems relating to obtaining sides of the triangle while trigonometric relations including :
Sinθ = opposite / hypotenus
Tanθ = opposite / Adjacent
Cosθ = Adjacent / Hypotenus
To obtain the angle θ; depending on which of the sides are given.
From Pythagoras :
c² = a² + b²
Where, c = hypotenus and the longest side if the triangle.
