Question

Evaluate: 2 tan 45°×cos60°/
sin30°

Answer 1

2

Explanation:

1. The easiest way to solve this is if you know your trig tables I will provide one as an example

2. Now that we know the value of each we can simply replace their respective values with the numbers

3.
`(2(1) *(0.5))/((0.5))` (I converted the fractions into decimals for the sake of making it more readable)

4. If we cancel both 0.5's out we are left with 2(1) which is just 2

Answer 2

2

Explanation:

2 tan 45°×cos60°/

sin30°

•tan45=1

•cos60=1/2

•sin30=1/2

•2×1×1/2/1/2

•2,,
