Find the value of x

Lostsunrise [7]

Step-by-step explanation:

In a right angle triangle one angle is 90°

w.k.t sum of angles in a triangle is 180°

thus, 2x+15+x+90°=180°

3x+105°=180°

3x=75°

x= 75/3=25°

Hope this helps you.

Find the sale pice is the original price is $82 and discount is 10%

Tpy6a [65]

First you should find the discount so you can say:
10/100 = ?/82
so ? is your discount and ? is equal to:
? = 82*10/100 = 8.2
so your discount is $8.2 and your sale price will be:
$82 - $8.2 = $73.8 :)))
I hope this is helpful
have a nice day

Please help with this precalc!!! i desperately need help

Paladinen [302]

Step-by-step explanation:

4 is the A or Ampltiude

To find the period set it equal to 2 pi/B

$\frac{2\pi}{b} = \frac{6}{1}$

$\frac{b}{2\pi} = \frac{1}{6}$

b=

$\frac{2\pi}{6}$

b=

$\frac{\pi}{3}$

There is no phase shift

The midline or d or vertical shift is 1.

Our equation for 8 is

$4 \sin( \frac{\pi}{6} x) + 1$

9.Use sin function. The a value is 2 or -2 your choice.

Set up the period equal to the equation

$\frac{2\pi}{b} = \frac{\pi}{3}$

$\frac{b}{2\pi} = \frac{3}{\pi}$

$b = \frac{3}{\pi} \times 2\pi$

Which equal 6.

B=6

There is no C and the D and Vertical Shift is 1.

Our equation is

$2 \sin(6x) + 1$
