The measure of an angle that forms a pair of same-side interior angles with that angle will be 55 degrees

<h3>Same side interior angles</h3>

Given the following parameters from the question;

sloping angle = 55 degrees

Since the room is parallel to the ceiling, the measure of an angle that forms a pair of same-side interior angles with that angle will be equal to the sloping angle.

Hence the required measure will be 55 degrees

Brut [27]
Since they give updates every 18 minutes, thus any time being a multiple of 18 after 2 pm will be the time they give update.

5:30 pm is 3 hours 30 minutes for 2 pm or 150 minutes from 2 pm.

In 150 minutes, there are eight 18 minutes that have passed and is remaining 6 minutes for the next multiple of 18.

Therefore, you have to wait for 6 minutes for the next weather update.

Find the center of the circle whose equation is x² + y² = 4.
Varvara68 [4.7K]

Answer:

The center of circle is (0,0)

Step-by-step explanation:

We need to find the center of the circle of the equation x^{2}+y^{2}=4

Since, the general equation of circle is (x-h)^{2}+(y-k)^{2} = r^{2}

Where (h,k) is center of circle and r is radius.

Re-write the circle equation is x^{2}+y^{2}=4 as,

x^{2}+y^{2}=2^{2}

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

so, (x-0)^{2}+(y-0)^{2} = 2^{2}

Hence, the center of circle is (0,0)

Which formula can be used to describe the sequence below? –8, –5, –2, 1, 4, ...
makvit [3.9K]

Answer:

an = -8 +3(n-1)

an = -11 +3n

f(n) = -11 +3n

Step-by-step explanation:

–8, –5, –2, 1, 4, ...

This is an arithmetic sequence.

We are increasing by 3 each time

-8 +3 = -5

-5+3 = -2

-2 +3 = 1

The common difference is 3

The formula for an arithmetic sequence is

an = a1 +d (n-1)

an = -8 +3(n-1)

an = -8 +3n -3

an = -11 +3n

The nth term is -11 +3n

f(n) = -11 +3n
