Question

Sin150°-5cos300°+7tan225°/tan135°+3sin210°​

Answer 1

Answer:

-2

Step-by-step explanation:

=sin(180-30)°- 5cos(360-60)°+ 7tan(270-45)°/tan (180-45)°+3sin (270-60)°

=sin30°-5cos60°+7cot45°/-tan45°-3cos60°

=1/2-5×1/2+7×1/-1-3×1/2

=-2

Hope you will understand

Answer 2

The value of the expression is -2.

Step-by-step explanation:

Consider the provided expression.

$\dfrac{\sin150-5\cos300+7\tan225}{\tan135+3\sin210}$

The above expression can be written as:

$\dfrac{\sin(180-30)-5\cos(360-60)+7\tan(180+45)}{\tan(90+45)+3\sin(180+30)}$

$\dfrac{\sin30-5\cos60+7\tan45}{-\tan45-3\sin30}$

$\dfrac{\frac{1}{2}-\frac{5}{2}+7\times1}{-1-\frac{3}{2}}$

$\dfrac{\frac{1-5+14}{2}}{\frac{-2-3}{2}}$

$-\dfrac{10}{5}=-2$

Hence, the value of the expression is -2.
