4 0

ANSWER

-4.0

EXPLANATION

The given trigonometric equation is

\tan \: 45 \degree - 10 \:  \cos \: 60 \degree

From special angles or using the unit circle.

\tan \: 45 \degree  = 1

\cos \: 60 \degree =  \frac{1}{2}

We make the substitution to get:

1 - 10 ( \frac{1}{2} ))

This simplifies to:

1 - 5 =  - 4

Hence the correct answer is -4.0
