Find the indicated side of the right triangle

Mathematics
2 answers:
Ludmilka [50]3 years ago

Answer:

9

Step-by-step explanation:

so to find x you have to use the tan ratio because x is the opposite of the angle at the top and you are given which is 9

tan45=opposite/adjacent

tan45=x/9

x=tan45×9

=9

I hope this helps

Answer:

x=9

y=9sqrt2

Step-by-step explanation:

Since it is a 45 45 90 triangle, the two side lengths are the same

But the hypoteneuse is always the side length time sqrt 2

What is the measure of L?<br> A. 390<br> B. 25°<br> C. Cannot be determined<br> D. 32°
Ulleksa [173]

Answer:

im pretty sure 25°

Step-by-step explanation:

Well the shape of an L is basically 1/4 of a rectangle. 1/4 is equal to 25 because 25 multiplied by 4 is 100. 100 divided by 4 is 25.

Answer:

\large\boxed{1.\ (-3, 0),\ r = 3}\\\boxed{2.\ (x+4)^2+(y-3)^2=36}\\\boxed{3.\ (x-2)^2+(y-1)^2=(\sqrt{34})^2}

Step-by-step explanation:

The equation of a circle in standard form:

(x-h)^2+(y-k)^2=r^2

(h, k) - center

r - radius

1. We have the equation:

(x+3)^2+y^2=9\\\\(x-(-3))^2+(y-0)^2=3^2

<h2 />

2. We have the center (-4, 3) and the radius r = 6. Substitute:

(x-(-4))^2+(y-3)^2=6^2\\\\(x+4)^2+(y-3)^2=36

3. We have the endpoints of the diameter: (-1, 6) and (5, -4).

Midpoint of diameter is a center of a circle.

The formula of a midpoint:

\left(\dfrac{x_1+x_2}{2};\ \dfrac{y_1+y_2}{2}\right)

Substitute:

h=\dfrac{-1+5}{2}=\dfrac{4}{2}=2\\\\k=\dfrac{6+(-4)}{2}=\dfrac{2}{2}=1

The center is in (2, 1).

The radius length is equal to the distance between the center of the circle and the endpoint of the diameter.

The formula of a distance between two points:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Substitute the coordinates of the points (2, 1) and (5, -4):

r=\sqrt{(5-2)^2+(-4-1)^2}=\sqrt{3^2+(-5)^2}=\sqrt{9+25}=\sqrt{34}

Finally we have:

(x-2)^2+(y-1)^2=(\sqrt{34})^2

*2. Formulate the number of daisies varied inversely as the number of sunflowers
lord [1]

There are 260 sunflowers  when there were 5 daisies and 100 roses

Given :

the number of daisies varied inversely as the number of sunflowers and directly as the number of roses.

Let 'd' be the daisies  and 's' be the sunflowers  and 'r' be the roses

Daises varies inversely as sunflowers and directly as roses

So, the equation becomes d=\frac{k(r)}{s}

where k is the constant

Lets find out 'k' using the given information

When there 65 daisies, there were 15 roses and 3 sunflowers

d=65, r=154 and s=3. Replace the values and find out k

d=\frac{k(r)}{s}\\65=\frac{k(15)}{3} \\65=5k\\Divide \; by \; 5\\k=13

Replace k with 13 in the equation

d=\frac{k(r)}{s}\\d=\frac{13(r)}{s}

Now we find out number of sunflowers using the above equation

d=5  and r=100 . Replace the values and find out 's'

d=\frac{13(r)}{s}\\5=\frac{13(100)}{s}\\5=\frac{1300}{s} \\multiply \; by \; s\\5s=1300\\divide \; by \; 5\\s=260

There are 260 sunflowers  when there were 5 daisies and 100 roses
