Answer:

sin(R)=6/sqrt(97)

Step-by-step explanation:

Sine is opposite/hypotenuse

If you want to know what the angle is, Angle R= about 37.5

Hope this helps

State if each angle is an inscribed angle. If it is, name the angle and the intercepted arc.

LUCKY_DIMON [66]

Answer:

No, there are no inscribed angle in this diagram; Option D

Step-by-step explanation:

~ Let us apply process of elimination to solve this problem ~

Option 1. This first example states firstly that m∠SRT is an inscribed angle. That is not true, by definition an inscribed angle is an angle created by two chords that share a common endpoint. Neither RS nor RT are chords, in fact they each are radii, creating a central angle instead.

Option 2. m∠RST is not created by two chords, instead by arc ST and radii RS ⇒ and I believe I am not familiar with what angle it is reffered to, if at all it is named.

Option 3. As stated before, ∠SRT is not an inscribed angle; by definition an inscribed angle is an angle created by two chords that share a common endpoint, and neither RS nor RT are chords.

Option 4. Through elimination, Option D is the only possible answer left: Answer: No, there are no inscribed angle in this diagram

Cube A has a volume of 9 in3. Cube B has a volume of 5 in3. Which of the following expresses the ratio of the side length of Cub

Troyanec [42]

Using the formula for the volume of a cube, it is found that the expression which gives the ratio of the side length of Cube A to the side length of Cube B is:

$r = \frac{3^{\frac{2}{3}}}{5^{\frac{1}{3}}}$

Which means that option E is correct.

The volume of a cube of side length l is given by:

$V = l^3$

For Cube A, the volume is of 9 cubic inches, hence:

$l_a^3 = 9$

$l_a = \sqrt[3]{9}$

$l_a = 9^{\frac{1}{3}}$

$l_a = 3^{\frac{2}{3}}$

For Cube B, the volume is of 5 cubic inches, hence:

$l_b^3 = 5$

$l_b = \sqrt[3]{5}$

$l_b = 5^{\frac{1}{3}}$

Then, the ratio is:

$r = \frac{l_a}{l_b} = \frac{3^{\frac{2}{3}}}{5^{\frac{1}{3}}}$

80 decreased by 3 times a number is the same as 5 times the number increased by 8 find the number.

faltersainse [42]

Answer:

The number is 5.

Step-by-step explanation:

Let the number be $x$ .

Given $80$ is decreased $3$ times $x$ .

$\implies 80 - 3x$

$5$ times the number increased by $8$ .

$5(x + 8)$

This means:

$8 - 3x = 5(x + 8)$

$\implies 8x = 40$

$\implies x = 5$

8. An isosceles triangle includes two 56' angles. Which equation could be

SSSSS [86.1K]

Answer:

B. x=180-2(56)

Step-by-step explanation:

Isosceles triangles have 2 angles of equal measure and 1 different measure. we add both measures or multiply them by 2 and then subtract them from 180 (sum of all angle measurements in a triangle) to find the missing measure
