Answer:
A) Tan 60°
= 1.732
B) H = 12 unit
C) Area of triangle = 41.569 unit²
Step-by-step explanation:
As shown in figure, the triangle with cone angle of 60° and base value 4
unit
A) Now, Tan 60° =
Or, Tan 60° = 1.732
B) To find value of h
since TanФ = ![\frac{Perpendicular}{Base}](https://tex.z-dn.net/?f=%5Cfrac%7BPerpendicular%7D%7BBase%7D)
So, Tan 60° =
= ![\frac{h}{4\sqrt{3} }](https://tex.z-dn.net/?f=%5Cfrac%7Bh%7D%7B4%5Csqrt%7B3%7D%20%7D)
∴(
) × (
= h
∴ h = 12 unit
C) Area of this triangle =
× Perpendicular × Base
=
× h ×![4\sqrt{3}](https://tex.z-dn.net/?f=4%5Csqrt%7B3%7D)
∵ Perpendicular h = 12 unit
So, Area =
× 12 × ![4\sqrt{3}](https://tex.z-dn.net/?f=4%5Csqrt%7B3%7D)
Hence Area of triangle = 41.569 unit²
