Answer:

Step-by-step explanation:

the triangle is a right triangle, meaning that we can use the pythagorean theorem to find a hypotenuse that will satisfy both Rs. if we use 3 as the radius, we get the hypotenuse as 2 + 3 = 5, where one leg is 3 and one is 4.

$\sqrt{} 3 {}^{2} + 4 { }^{2} = 5$

so we know that a radius of 3 is right

In the smaller triangle, let $y$ be the length of the smallest leg. Then the smallest leg in the larger triangle is $14-y$ .

Within the scope of the smaller triangle, we have $y$ such that

$x^2+y^2=13^2\implies y=\sqrt{13^2-x^2}$

Then within the larger the triangle, we would have

$x^2+(14-y)^2=15^2\iff x^2+\left(14-\sqrt{13^2-x^2}\right)^2=15^2$

Now we can solve for $x$ :

$x^2+14^2-28\sqrt{13^2-x^2}+(13^2-x^2)=15^2$

$\implies x=12$

There are four more girls than boys in Ms. Raub's class of 28 students. What is the ratio of number of girls to the number of bo

FinnZ [79.3K]

So there are x girls and x-4 boys and together they make 28:

x+x-4=28
2x-4=28
2x=32
x=16

so there are 16 girls and 12 boys.

the ratio is then 16:12, or we can simplify (by dividing both sides by 4): 4:3

so the best answer is 4:3.

I need help with this question asap pleaseeeeee

Answer:

y = 3 $\sqrt{7}$

Step-by-step explanation:

The two inner right triangles are similar, thus the ratios of corresponding sides are equal, that is

$\frac{y}{9}$ = $\frac{7}{y}$ ( cross- multiply )

y² = 63 ( take the square root of both sides )

y = $\sqrt{63}$ = $\sqrt{9(7)}$ = $\sqrt{9}$ × $\sqrt{7}$ = 3 $\sqrt{7}$

Provide an Example of how to draw transformed figures that are translated, reflected, and rotated.

solniwko [45]

Step-by-step explanation:

Translations: When a figure is slid to another place on the coordinate grid (for example if i asked you to move the figure 2 units down and 4 units to the left)

Reflected: When a figure is reflected across the y-axis or the x-axis and both figures are congruent to each other.

Rotated: When a figure is rotated (for example if i asked you to rotate the figure 90 degrees)
