Question

Find the value of (i) 4 sin 30° + 5 tan 45°

Answer 1

$4 \sin(30) + 5 \tan(45) \\ = \frac{4}{2} + 5 \times 1 \\ = 7$
please follow me

Answer 2

$since \: \sin(30) = \frac{1}{2} \\ \\ and \: \tan(45) = 1 \\ \\ therefore \\ \\ 4 \sin(30) + 5 \tan(45) \\ \\ = 4 \times \frac{1}{2} + 1 \times 5\\ \\ = 2 \times 1 + 5\\ \\ = 2 + 5 \\ \\ = 7 \\ \\ hope \: it \: helps.......$
