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)
Answer:
Step-by-step explanation:
Well flat means open so 180°
180° - 50° = 130° is the answer
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°
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!!!
