In circle O, m∠R = 30.8°. Find m∠NOQ.

nordsb [41]

Given:

In circle O, m∠R = 30.8°.

To find:

The m∠NOQ

Solution:

Central angle theorem: According to this theorem, the central angle is always twice of subtended angle on the same arc.

Angle NOQ and angle NRQ are on the same arc but ∠NOQ is the central angle and ∠NRQ is the subtended angle on the arc NQ.

Using central angle theorem, we get

$m\angle NOQ=2\times m\angle NRQ$

$m\angle NOQ=2\times m\angle R$

$m\angle NOQ=2\times 30.8^\circ$

$m\angle NOQ=61.6^\circ$

Therefore, $m\angle NOQ=61.6^\circ$ .

If instead of randomly selecting two people there were five, what is the probability that all five are right-handed

lozanna [386]

Answer:

1/32

Step-by-step explanation:

We can break this question down. If we had 1 person and they are right-handed, the probability is 1/2 because they are either left-handed or right-handed. Knowing that, we can multiply the probability of having 1 person being right-handed 5 times because there are 5 people in the question.

1/2 × 1/2 × 1/2 × 1/2 × 1/2 = 1/(2⁵) = 1/32

Therefore, the probability of randomly selecting 5 people who are right-handed is 1/32.

I hope this helps and please mark me as brainliest!

A rectangle has a height of 2x^4 with a width of x^2+8x+15. Express the area of the rectangle.

Amiraneli [1.4K]

Hi there!

We know that the formula for the area of a rectangle is height * width. Thus, we can multiply these two expressions together:

$2x^4\cdot (x^2+8x+15)\\$

Now, we know through the distributive property that we can distribute the $2x^4\\$ to everything in the parenthesis. Once this is done, we get:

$2x^4 \cdot x^2+2x^4\cdot8x+2x^4\cdot15$

Now, we know through the power rule that when two exponents are multiplied together with the same base, the exponent can be added together $(x^a \cdot x^b = x^{a+b})$ . This then would make our equation:
