Explain how the tangents of complementary angles are related.
dezoksy [38]

Answer:

  tan(α) = 1/tan(90°-α)

Step-by-step explanation:

The tangent of one is the reciprocal of the tangent of the other.

__

In a right triangle, ...

  tan = opposite/adjacent

For the two complementary acute angles in such a triangle, opposite and adjacent are swapped. That is the tangent of one is the inverse of the tangent of the other. (That inverse is also known as the cotangent.)

  tan(α) = cot(90°-α) = 1/tan(90°-α)

Help!! What is arc HLK? Thankyou!
Bezzdna [24]

We know Angle HMK is half the sum of Arc JI and Arc HLK. So, we can set up an equation.

8x - 1 = 1/2 (3x + 2 + 15x - 36)

8x - 1 = 1/2 (18x - 34)

16x - 2 = 18x - 34

32 = 2x

16 = x

Then, we can substitute x into Arc HLK

HLK = 15x - 36

HLK = 240 - 36

Arc HLK = 204°

In a recent year, person A and person B had the two top-grossing concert tours, together generating about $300 million in ticket
Brrunno [24]

Answer: Person B had $114,000,000 and person A had $186,000,000

Step-by-step explanation:

You do $300 million divided by 2 to get 150,000,00 and then subtract 150,000,000 - 38,000,000= 114,000,000 and that's for person B and than you  add the 38,000,000  to the 150,000,000 to get the amount person A had.

There you go!!!
