Cos(-170°) = _____ -cos10° cos10° cos(-10°)

Mathematics
1 answer:
Lera25 [3.4K]3 years ago
7 0

Answer:

<h3>-cos10°</h3>

Step-by-step explanation:

cos is positive at first and fourth quadrant

so, cos (-x) = cos (x)

also, cos(180-x) = -cos x

        cos (180+x) = -cos x

cos (-170°) = cos (170°)

cos(170°) = cos (180° - 10°)

              =  - cos 10°

The first 32 whole numbers are evenly spaced around the circumference of a circle. Which number will be opposite of 26?
Ludmilka [50]

Answer:

"10"

Step-by-step explanation:

This is rather thinking "pictorially". Picture it.

You can match it with a round clock that has numbers 1 - 12 written on it.

So,

32 and 16 would be opposite of each other [top and bottom]. And, 1 - 15 would be on right side and 17 - 31 would be on left side.

Now,

Going counter-clockwise from 32, 26 would be the 6th number. Going counter-clockwise from 16, 10 would be the 6th number.

Hence, they would be opposite of each other.

10 would be opposite of 26
