The value of X is 56.66°. The sine of X (opposite/hypotenuse) is 66mm/79mm. When finding angle measurements, you would use sin−1 instead of sin, which is used for finding side lengths. So, X= sin−1(66/79). This then results to 56.66° after using the trig functions in a calculator.

Answer:

5.495%

Step-by-step explanation:

Find the percent change by dividing the difference in prices by the original price, then multiplying it by 100

(10.99 / 200) x 100

0.05495 x 100

= 5.495

So, the percent change is 5.495%

Find the value of x in the equation 2x²+3x+3=20

Zigmanuir [339]

Answer:

$x= \frac{-3 - \sqrt{145} }{4} \ \ or\ \ x= \frac{-3 + \sqrt{145} }{4}$

Step-by-step explanation:

2x² + 3x + 3 = 20

⇔ 2x² + 3x + 3 - 20 = 0

⇔ 2x² + 3x - 17 = 0

<u>Using the Quadratic Formula to solve a Quadratic Equation</u> :

$x= \frac{-b \pm \sqrt{b^{2}-4ac} }{2a}$

In the equation 2x² + 3x - 17 = 0

a = 2 , b = 3 and c = -17

Then

b² - 4ac = 3² - 4×2×(-17)

= 9 + 8 × 17

= 9 + 136

= 145

Then

b² - 4ac > 0

Then

$x= \frac{-3 \pm \sqrt{145} }{2 \times 2}$

Then

$x= \frac{-3 \pm \sqrt{145} }{4}$

Which expression is equal to 3(56)?

kakasveta [241]

168. When a number is in parenthesis, you just multiply, so multiply the 3 times the 56 to get 168.
