Find the exact value of tan 195 degrees

melamori03 [73]

Answer:

$tan(195\°)=tan(15\°)=0.267949192431123...$

Step-by-step explanation:

We know that

$tan(195\°)=tan(15\°)$ , because $195\° - 180\° = 15\°$ .

Now, angle 15° or 195° is not an important angle which can be solve by a given table like 30°, 45° or 60°. This means we have to use the calculator to find the more exact value, which is

$tan(195\°)=tan(15\°)=0.267949192431123...$

What is the next three terms in sequence of 8, 20, 50

krek1111 [17]

This sequence is doubling the sequence and adding half. When n is your number, you could find the next number in your sequence by plugging in the number:

2n+0.5n

To find the 4th term, we need to plug in 50.

2*50+0.5*50=125

Now, we need to find the 5th term, so we plug in 125.

2*125+0..5*125=312.5

To find the 6th term, we plug in 312.5.

2*312.5+0.5*312.5=781.25

So, the next 3 terms are 125, 312.5, and 781.25

Anybody happen to know this? Help please

polet [3.4K]

Answer:

It's B, 62.

First, you identify the median, (30,) and use this to identify the first and third quartiles. 2-18 are the first ranges, and 42-81 are the third.

You would need to split the ranges between the first quartile (9) and the third quartile (71).

The interquartile range is the difference between the first and third ranges, making it 62.

What is the approximate area of the shaded sector in the circle shown below

harina [27]

Answer:

Option A. 283 cm²

Step-by-step explanation:

to find the area of the shaded sector, we use the formula:

$\frac{\text{angle given}}{360^\circ}\times \text{area of the circle}$

where area of the circle = πr²

∴ for the given circle,

$\text{Area of the sector}=\frac{\text{given angle}}{360^\circ} \times \pi r^2$

= $\frac{100}{360}\times 3.14\times 18\times 18$

= $\frac{100}{360}\times 1017.36$

= 282.6

≈ 283 cm²

The approximate area of the shaded sector is 283 cm².
