Use a half-angle identity to find the exact value
Tatiana [17]

Given:

\cos 15^{\circ}

To find:

The exact value of cos 15°.

Solution:

$\cos 15^{\circ}=\cos\frac{ 30^{\circ}}{2}

Using half-angle identity:

$\cos \left(\frac{x}{2}\right)=\sqrt{\frac{1+\cos (x)}{2}}

$\cos \frac{30^{\circ}}{2}=\sqrt{\frac{1+\cos \left(30^{\circ}\right)}{2}}

Using the trigonometric identity: \cos \left(30^{\circ}\right)=\frac{\sqrt{3}}{2}

            $=\sqrt{\frac{1+\frac{\sqrt{3}}{2}}{2}}

Let us first solve the fraction in the numerator.

            $=\sqrt{\frac{\frac{2+\sqrt{3}}{2}}{2}}

Using fraction rule: \frac{\frac{a}{b} }{c}=\frac{a}{b \cdot c}

            $=\sqrt{\frac {2+\sqrt{3}}{4}}

Apply radical rule: \sqrt[n]{\frac{a}{b}}=\frac{\sqrt[n]{a}}{\sqrt[n]{b}}

           $=\frac{\sqrt{2+\sqrt{3}}}{\sqrt{4}}

Using \sqrt{4} =2:

           $=\frac{\sqrt{2+\sqrt{3}}}{2}

$\cos 15^\circ=\frac{\sqrt{2+\sqrt{3}}}{2}

In the following diagram, parallelogram ABCD contains triangle CED. Line CE and line ED intersect at point E. The measures of ∠C
nirvana33 [79]

Answer:

∠x = 59°

Step-by-step explanation:

∠ECD = 52°   because they are alternate angles and will be equal

∠x = 180° - 52° - 69° = 59°  because the sum of the interior angles of a triangle = 180°

1.) The answer is 825.75 (multiply the given tax rates to the gross pay)
    2,785 x 13% federal taxes = 362.05
    2,785 x 9% state tax         = 250.65
    2,785 x 7.65% FICA          = <u>213.05
</u>                                                 825.75
<u>
</u>2.) The answer is 288.60 (multiply the interest rate to the balance, no need to add a late payment fee since they paid on 6/1, not after)
    2,748.56 x 10.5% = 288.60

3.) The answer is 182.13  (multiply the APR to the original purchase price, no need to add the sales tax)
<u />    1,500 x 11.75% = 182.13

4.) The answer is 371.92 (deduct the reward to the interest)
    Interest : 2,975.34 x 13.5% = 401.67
    Reward : 2,975.34 x 1%      = <u>  29.75</u>  
                                                    371.92

5.) The answer is  1,339.13 (deduct the interest to the monthly payment)
    Monthly payment : 2,236.00
    Monthly interest :   <u>   896.87</u> [(231,450 x 4.65%) / 12 months]
<u />                                    1,339.13

Hope this helps! :)
