Answer: x=18 ; y=6\sqrt{3}

Step-by-step explanation:

You can write two expressions that are in terms of 'x' and 'y'. This is a right triangle, so Pythagorean's theorem can be used. We can also use the angle to find the sine of 30 degrees.

<u>Pythagorean's Theorem:</u>

The values 'a' and 'b' are the two shorter sides of the triangle, while the value 'c' is the longest side of the triangle; the hypotenuse.

a^2+b^2=c^2

x^2+y^2=(12\sqrt{3} )^2

x^2+y^2=12^2*\sqrt{3} ^2=432

<u>Sine of the Angle:</u>

Sine is defined to be the opposite side divided by the hypotenuse. Let's take the sine of 30 degrees:

sin(\alpha )=opposite/hypotenuse

sin(30)=y/12\sqrt{3}

\frac{1}{2} =y/12\sqrt{3}

y=6\sqrt{3}

Plug this value of 'y' into the first expression derived from Pythagorean's theorem:

x^2+y^2=432

x^2+(6\sqrt{3} )^2=432

x^2+108=432

x^2=432-108=324

x=\sqrt{324}

x=18

Use this value of 'x' to solve for 'y' in the expression from Pythagorean's theorem:

(\sqrt{324})^2+y^2=432

324+y^2=432

y^2=432-324=108

y=\sqrt{108}

y=\sqrt{36*3}

y=6\sqrt{3}

How many ways can Carlos choose 2 pizza toppings from a menu of 4 toppings if each topping can only be chosen once?
Ahat [919]

Answer:

30 different ways

Step-by-step explanation:

Hi

for the first topping she can choose 1 of 6 items

so she has 6 choices

and then the second topping she has 5 choices as each topping can only be chosen once

so it comes 6 * 5 = 30

Find the equation of a line perpendicular to y - 12 = 2x – 8 that passes through the point (2, 3). (answer in slope-intercept fo
Alla [95]

Answer:

\displaystyle y=-\frac{1}{2}x+4

Step-by-step explanation:

<u>Equation of a Line</u>

We can find the equation of a line by using two sets of data. It can be a pair of ordered pairs, or the slope and a point, or the slope and the y-intercept, or many other combinations of appropriate data.

We are given a line

y - 12 = 2x -8

And are required to find a line perpendicular to that line. Let's find the slope of the given line. Solving for y

y = 2x +4

The coefficient of the x is the slope

m=2

The slope of the perpendicular line is the negative reciprocal of m, thus

\displaystyle m'=-\frac{1}{2}

We know the second line passes through (2,3). That is enough information to find the second equation:

y-y_o=m'(x-x_o)

\displaystyle y-3=-\frac{1}{2}(x-2)

Operating

\displaystyle y=-\frac{1}{2}(x-2)+3

Simplifying

\displaystyle y=-\frac{1}{2}x+4

That is the equation in slope-intercept form. Intercept: y=4
