NEED RN, WORTH 20! <br> What is the value of x?
max2010maxim [7]

Answer:

x = 5.625

Step-by-step explanation:

<u>Step 1:  Make an expression</u>

<u />\frac{3}{4} = \frac{x}{7.5}

<u>Step 2:  Cross Multiply</u>

<u />\frac{3}{4} = \frac{x}{7.5}

4 * x = 7.5 * 3

4x = 22.5

<u>Step 3:  Divide both sides by 4</u>

<u />4x / 4 = 22.5 / 4

x = 5.625

Answer:  x = 5.625

Please help me with this pleaseee
torisob [31]

Answer:

x = 88.2

Step-by-step explanation:

The angle at the top of the triangle = 90° - 10° = 80°

and the left side of the triangle is x ( opposite sides of a rectangle )

Using the tangent ratio in the right triangle

tan80° = \frac{opposite}{adjacent} = \frac{500}{x}

Multiply both sides by x

x × tan80° = 500 ( divide both sides by tan80° )

x = \frac{500}{tan80} ≈ 88.2

What is the equation of the circle whose center and radius are given.
muminat
Hello!

The equation for a circle is

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

(h,k) is the center
r is the radius

Put in the values you know

(x - 7)^{2} + ( y + 3)^{2} = 7^{2}

Simplify

(x - 7)^{2} + ( y + 3)^{2} = 49

The equation is (x - 7)^{2} + ( y + 3)^{2} = 49

Hope this helps!
