There are 2 way to solve this.

one using Pythagoras theorem and 2nd using trigonometry

so lets solve it by both

using Pythagoras theorem we know

base^2 + perpendicular^2 = hypotanes^2

6^2 + x^2 = 12^2

36 + x^2 = 144

x^2 = 144- 36 = 108

x = √(108) = √( 2×2×3×3×3)

= (2×3) √ (3) = 6 √3

so answer is option 2

bow lets use trigonometry

we know
sin theta = perpendicular / hypotanes
sin 60 = x /12
x = 12 × sin 60
we kNow sin 60 = √3/ 2
so
x = 12×√3 /2 = 6√3

What is the sales tax of a $15.95 video game if the tax rate is 7%​
harina [27]

Answer:

$17.07

Step-by-step explanation:

Step 1: Find the percent of the price

Convert 7% to fraction

= \frac{7}{100}\\\\=\frac{7}{100}\times \:15.95

Multiply

=\frac{7\times \:15.95}{100}

Multiply the factors

7\times \:15.95=111.65\\\\=\frac{111.65}{100}

Divide

\frac{111.65}{100}=1.1165\\\\=1.1165

Step 2: Add the percent off to the original price

15.95 + 1.1165\\\\= 17.0665

Therefore, the total cost including tax in the nearest cent is 17.07 dollars
