I’m really confused on this one and want to make sure. I’ll make you brainlest if you add explanation. Pls and thank you :))

Darya [45]

Answer:

$\sqrt{3}$

Step-by-step explanation:

See attachment 1. This is the formula to use.

There are two numbers, so n=2. Plugging them into the formula, you get

$\sqrt[2]{6*\frac{1}{2}} \\$

Now, putting a 2 in front just means we're finding the square root, so I'll get rid of it. Then, just do the calculation.

$\sqrt{6*\frac{1}{2}}=\sqrt{\frac{6}{2}}=\sqrt{3}$

Which of the following are magnitudes for rotational symmetry of the rectangle below about the marked point?

stira [4]

Answer:

The answer is B.180°.

Step-by-step explanation:

The figure is rotationally symmetric is after a rotation of a given angle, it still look the same.

In this case of a rectangle, the only way to rotate it so that is look the same, is by rotating it by multiple of 180°, so that the up and down sides flip over, as well as the right and left sides.

Therefore, the only option that applies is B.180°

Two angles form a linear pair. The measure of one angle is 2/3 the measure of the other angle. Find the measure of each angle

Luba_88 [7]

Answer:

108° and 72°

Step-by-step explanation:

let one angle be x then the other angle is $\frac{2}{3}$ x

the sum of the 2 angles = 180°, hence

x + $\frac{2}{3}$ x = 180 ( combining the left side )

$\frac{5}{3}$ x = 180

multiply both sides by 3 then divide both sides by 5

5x = 540 ⇒ x = 108

the 2 angles are x = 108° and $\frac{2}{3}$ x = 72°
