0 is in quadrant III and cos^2 0=1/4

Answers

Answer:

θ = 240

and

cos(θ) = -0.5

Step-by-step explanation:

Theta is in the third quadrant, that meansit goes from 180 to 270 degrees

Then,

cos^2 (θ) =1/4

cos (θ) = ± 1/2

θ = arccos(0.5)

θ = 60

But in the third quadrant

θ = 180 + 60  = 240

θ = 240

and

cos(θ) = -0.5

If,
2=5
3=10
4=17
5=??

Answers

In all the cases, the number is multiplied by itself and added 1 to it. so the answer is 26

Answer: 26

There is a pattern. It is squared then added with one.

For visual reference-

2=5 (2*2=4, 4+1=5)

3=10 (3*3=9, 9+1=10)

4=17 (4*4=16, 16+1=17)

5=?? (do the same thing)

so

5=26 (5*5=25, 25+1=26)
