Solve 50*sin30^circ+60*cos60^circ

$$50 \times \sin 30 ^ { \circ } + 60 \times \cos 60 ^ { \circ }$$

Evaluate

$$55$$

Solution Steps

Get the value of \sin(30) from trigonometric values table.

$$50\times \frac{1}{2}+60\cos(60)$$

Multiply 50 and \frac{1}{2} to get 25.

$$25+60\cos(60)$$

Get the value of \cos(60) from trigonometric values table.

$$25+60\times \frac{1}{2}$$

Multiply 60 and \frac{1}{2} to get 30.

$$25+30$$

Add 25 and 30 to get 55.

$$55$$
