the sum of complimentary angles equal 90°.
x + 58° = 90°
x = 32°
cos (32°) = 0.848
Answer: B
Note: you can also take sin (58°) to get the answer.
Answer:
![-6(x^2+3x+4)](https://tex.z-dn.net/?f=-6%28x%5E2%2B3x%2B4%29)
Explanations:
The given expression is
![-6x^2-18x-24](https://tex.z-dn.net/?f=-6x%5E2-18x-24)
This can be factored as shown below:
Answer:
the diameter of a circle is 56 CM
The angle ∠JKN is 79°
A figure which is formed by two rays or lines that shares a common endpoint is called an angle. A bisector divides an angle into two equal angles.
∠JKN = (8x - 13)° (given)
∠NKL = (6x +11)° (given)
∠JKN = ∠NKL ( As KN bisects ∠JKL )
8x - 3 = 6x + 11 ( substituting equations from question )
8x - 6x = 11 + 3 ( bringing like terms on same side)
2x = 23
x = 23/2
x = 11.5
Now, put value of x in the given equation: ∠JKN = (8x - 13). we get
∠JKN = (8x - 13)
∠JKN = (8*11.5 - 13)
∠JKN = (92 - 13)
∠JKN = 79°
Therefore, We can conclude that the angle ∠JKN is 79°.
