Question

find the value of sin,cos and tan

Answer 1

this is the answer of question.

Answer 2

Heya!!

Since, angle XMZ = 90°

In triangle XMZ ,

By pythagoras theorem,

ZX^2 = MZ^2 + MX^2

=) 20^2 = 16^2 + MX^2

=) MX^2 = 400-256

=) MX = root 144

=) MX = 12 cm

Now,

In triangle MYX

By pythagoras theorem,

XY^2 = MY^2 + MX^2

=) XY^2 = 5^2 + 12 ^2

=) XY^2 = 25 + 144

=) XY = root 169

=) XY = 13 CM

NOW,

IN TRIANGLE MYX,


Sin theta = perpendicular/hypotenuse

= MY/XY

= 5/13

Cos theta = base/ hypotenuse

= MX/XY

= 12/13

Tan theta = perpendicular/ base

= MY/MX

= 5/12

Hope it helps u.
