Answer:

360

Step-by-step explanation:

All circles can be divided into 360 units called degrees. Since there is 270 already we subtract 270 from 360.

360 - 270 = 90

90 + 150 + 120 = 360

Using sum or difference formulas, find the exact value of sin(165∘)

Nikitich [7]

$\bf \textit{Sum and Difference Identities}
\\ \quad \\
sin({{ \alpha}} + {{ \beta}})=sin({{ \alpha}})cos({{ \beta}}) + cos({{ \alpha}})sin({{ \beta}})
\\ \quad \\
sin({{ \alpha}} - {{ \beta}})=sin({{ \alpha}})cos({{ \beta}})- cos({{ \alpha}})sin({{ \beta}})\\\\
-------------------------------\\\\$

$\bf sin(165^o)\implies sin(120^o+45^o)
\\\\\\
sin(120^o)cos(45^o)~+~cos(120^o)sin(45^o)\implies \cfrac{\sqrt{3}}{2}\cdot \cfrac{\sqrt{2}}{2}~+~\cfrac{-1}{2}\cdot \cfrac{\sqrt{2}}{2}
\\\\\\
\cfrac{\sqrt{6}}{4}~-~\cfrac{\sqrt{2}}{4}\implies \cfrac{\sqrt{6}-\sqrt{2}}{4}$

a group of friends went to lunch the bill sales tax and tip was 48.60 a sales tax of 7% was added the group then tipped 18% on t

Usimov [2.4K]

Answer:

Sales tax = $2.79

Step-by-step explanation:

(18 x 48.6) /100

= 8.748 = $8.75 tip amount total

48.60-8.748 = 39.852 sales total

(39.852 x 7)/100

= 2.78964 = $2.79 sales tax

39.852 - 2.78964 = 37.06236 = $37.06 cost of bill

Sales tax was asked = $2.79
