25 POINTS!!PLEASE HELP Given tan(0)=5/6, then cos(0)=a/b. Determine the values of a and b

Value of a= 6

Value of b= 7.81

Step-by-step explanation:

We are given

and

We need to find values of a and b

We know that:

While

So, a = Base and b= Hypotenuse

We know the value of base i,e

We get Base=6, Perpendicular = 5

To find Hypotenuse we can use Pythagoras theorem

The value of hypotenuse is 7.81

The value of Base is 6

So,

Value of a= 6

Value of b= 7.81

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
