Give the value of x .<br><br> A. 60 degrees<br> B. 180 degrees<br> C. 120 degrees<br> D. 45 degrees

Harrizon [31]

Answer:

x=120°

Step-by-step explanation:

sum of all angles in a triangle is equal to 180

let the unknown angle be

$\alpha$

$60 + 60 + \alpha = 180 \\ \alpha = 180 - 60 - 60 \\ \alpha = 60 \\$

$\alpha + x = 180 \\ x = 180 - \alpha \\ x = 180 - 60 \\ x = 120$

Which is the best estimate to the nearest one percent of startfraction 7 over 15 endfraction?

ipn [44]

The best estimate to the nearest one percent of the fraction; 7/15 is; 47%.

<h3>What is the best estimate of the fraction to the nearest percent?</h3>

From the task content, it follows that the fraction given whose estimate is to be determined is; 7/15.

The fraction expressed as a percentage is;

(7/15) × 100 %

= 46.667%.

Hence, when rounded to the nearest one percent; = 47%.

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

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

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

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

$\frac{\pi}{3}$

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

$2 \sin(6x) + 1$
