nilai dari sin 30 derajat tan 60 derajat +sin 45 derajat cos 30 derajat =

(Sin30°•tan60°) + (Sin45°•Cos30°)
= (1/2•√3) + (1/2√2•1/2√3)
= 1/2√3 + 1/2√2 • 1/2√3
= 1/2√3 • 1/2√3 + 1/2√2
= 1/4•3 + 1/2√2
= 3/4 + 1/2√2
–Maaf ya kalau salah

1/2.√3+1/2√2.1/2√3
= 1/2√3+1/4√6
=1/2√3*2+1/4√6*1
=2/4√6=1/4√6
=3/4√6
