What is the measure of RPQ

patriot [66]

Answer:

239

Step-by-step explanation:

SP is the diameter so Arc RP is supplementary to Arc SR

$31 + x = 180$

$x = 149$

Arc PQ is supplementary to Arc SQ so

$90 + x = 180$

$x = 90$

Arc Addition:

$149 + 90 = 239$

If a right triangle's hypotenuse is 17 units long, and one of its legs is 15 units long, how long is the other leg?

Vesna [10]

Answer:

8 units

Step-by-step explanation:

Hello!

So, there's a formula we can apply to right-angled triangles: Pythagorean's theorem. It states that c = $\sqrt{{a}^2 + b^{2} }$ , where c is the hypotenuse and a and b are the legs of the triangle.

So, from the problem, if c = 17 and a = 15, then, we're solving for b. So we'll rewrite the theorem to solve for b.

${c}^2 = {a}^2+{b}^2\\{c}^2-{a}^2={b}^2\\{b} = \sqrt{{c}^2-{a}^2}$

Okay, so now we have isolated the theorem for b. Let's plug in our values for c and a.

$b = \sqrt{{17}^2-{15}^2}\\b = \sqrt{289-225}\\b = \sqrt{64}\\b = 8$

So, using the theorem, we found b = 8. To check our work, let's plug in b and a and solve for c.

$c = \sqrt{{a}^2+{b}^2}}\\c = \sqrt{{15}^2+{8}^2}\\c = \sqrt{225+64}\\c = \sqrt{289}\\c = 17\\$

So, we got our hypotenuse to equal 17 units, which is correct! So, our b is correct too. Awesome

Nine times the product of a negative two and a number

Aleksandr-060686 [28]

The statement written as a simplified mathematical expression is -18x

<h3>Writing mathematical expression</h3>

From the question, we are to write the given statement as a mathematical expression

The given expression is,

"Nine times the product of a negative two and a number"

Let the number be x

Thus,

The product of negative 2 and a number means

-2 × x = -2x

Then,

Nine times the product of a negative two and a number is

9 × -2x = -18x

Hence, the statement written as a simplified mathematical expression is -18x
