Question

find the value of 2tan 45° +cos30° - sin 60° complete the activity : 2tan 45° +cos 30° - sin60° =2 × 1 + _____ - ______ = 2 + _______ = _______ .​

Answer 1

hey mate, hope this helps u

tan 45*=1

cos 30*=$\sqrt{3} /2$

sin 60*=$\sqrt{3} /2$

then,.... 2 tan45*=2(1)=2

            +cos 30*=$\sqrt{3} /2$

            -sin 60*= -$\sqrt{3} /2$

2tan 45*+cos30*-sin60*=2(1) +$\sqrt{3} /2$ -$\sqrt{3} /2$= 2+0=2

Answer 2

Step-by-step explanation:

tan45⁰=1

2(1)

2

cos30⁰=√3/2

sin60⁰=√3/2

2 + √3/2 - √3/2

2+0

2

so first aur second dono me √3/2 aayega

third me 0

forth me 2 aayega
