Question

Mini Exercise
In a right angled triangle
length of base is 4 cm and
its perpendicular is 3 cm.
Find:
(i) length of hypotenuse
(ii) sin e
(iii) cos e
(iv) tan e​
(e stands for theta)

Answer 1

Answer:

Following are the answers:

(i) Let perpendicular be AB i.e.

AB=3

Let base be BC i.e.

BC=4

For hypotenuse:(AC)

AC= √AB^2+BC^2

AC=√25

AC=5

so,

(ii) sin e= Perpendicular/hypotenuse

sine=3/5

(iii) cose= Base/hypotenuse

cose=4/5

(iv) tane= Perpendicular/base

tane=3/4
