1+ \sqrt{3}
tangent 60 is √3 on the unit circle and tangent 225 is 1. So 1+√3 is the exact value of tan 60 plus tan 225

We need to find exact value of Tan 60+Tan 225°

We apply the reference angle by finding the angle with equivalent trigonometrical values in the first quadrant.

On the trig unit circle,

tan 225 = tan (45 + 180) = tan 45 = 1.

The exact value of tan(45) is 1.

The exact value of Tan 60° = \sqrt{3}..

Substituting Tan225 and Tan60 values we have:

Tan 225°+Tan60°= 1+\sqrt{3}.

Step-by-step explanation:

P(green) = 45 / 139

P(yellow) = 20 / 139

Add them together for either one:

65 / 139 = 0.468 = 46.8%

A student is saving at least $5,000 for college. She begins with a savings account set up by her parents containing $2,000. Each
rosijanka [135]

Answer:

5000 ≥ 2000 + 50a

Step-by-step explanation:

She wants to save at least $5000 for college. The saving account set up by her parents already contains $2000 . This means she has more $3000 to save to meet her minimum target. Each month she saves $50 into the account.

Let

number of month = a

The information can be expressed as follows

5000 ≥ 2000 + 50a

The savings will continue increasing every months because she always deposit $50 every month.

Using the expression

5000 ≥ 2000 + 50a

minus 2000 from both sides

3000 ≥ 50a

divide both sides by 50

3000/50 ≥ a

60 ≥ a

This means she needs at least 60 months to meet her savings/target.
