Find the lengths of the missing sides in the triangle. Write your answers as integers or as decimals rounded to the nearest tent

nalin [4]

Answer:

The last one $(x=11.3, y=8)$ .

Step-by-step explanation:

1) There are three trigonometric ratios for right-angled triangles.

$sin()=\frac{opposite}{hypotenuse}\\cos()=\frac{adjacent}{hypotenuse}\\tan()=\frac{opposite}{adjacent}$

In a right triangle, the hypotenuse, h, is the side opposite the right angle. Relative to the acute angle θ, check the attachment, the legs are called the opposite side, o, and the adjacent side a.

2) In this case, we are given a length and an angle to find x and y.

Let's find x first. To find x we need to use $sin()=\frac{opposite}{hypotenuse}$ .

$sin(45)=\frac{8}{x}\\sin(45)x=8\\x=\frac{8}{sin(45)} \\x=11.31$

Find y.

Notice that, we can use the Pythagorean Theorem $(c^2=a^2+b^2)$ to find y.

$c^2=a^2+b^2$

$11.31^2=8^2+b^2\\11.31^2 - 8^2 = b^2\\63.9161 = b^2\\\sqrt{63.9161} = b\\b = 7.99$

3) Round them off to the nearest tenth.

$x=11.31\\x=11.3$

$y=7.99\\y=8$

Therefore, the correct choice is the last one $(x=11.3, y=8)$ .

In 2014, the enrollment at Luling High School was 625 students. In 2015, the enrollment grew to 650. By what percentage did the

Inessa05 [86]

Answer:

$\%Increase = 4\%$

Step-by-step explanation:

Given

$Initial\ Population = 625$

$Final\ Population = 650$

Required

Determine the percentage population increase

This is calculated using the following formula:

$\%Increase = \frac{Final - Initial}{Initial} * 100\%$

$\%Increase = \frac{650 - 625}{625} * 100\%$

$\%Increase = \frac{25}{625} * 100\%$

$\%Increase = \frac{25* 100\%}{625}$

$\%Increase = \frac{2500\%}{625}$

$\%Increase = 4\%$

<em>Hence, there is a 4% increment from 2014 to 2015</em>
