Answer:
tanΘ = -
Step-by-step explanation:
Using the trigonometric identity
tan²Θ + 1 = sec²Θ, thus
tan²Θ + 1 = ( )² =
( subtract 1 from both sides )
tan²Θ = ( take the square root of both sides )
tanΘ = ±
Since 270 < Θ < 360 , that is the fourth quadrant where tan Θ < 0, thus
tanΘ = -
It is given that,
Area of the triangle is calculated as,
Thus the base of the given right angled triangle is 8 m.
