The sum of 5 consecutive integers is 120. what is the third number in the sequence
rosijanka [135]
The sum of 5 consecutive integers is 120
third number = ?
third number will be the middle number of 5 consecutive integers
so if we divide 120 with 5 we get 24.
so 24 is the third number.
consecutive numbers are: 22, 23,24,25 and 26
22 + 23  +24 +25 +26 = 120
so, 24 is the third number

What is sin -1 (1/2) if the terminal side of 0 is located in quadrant 1
Lady_Fox [76]

Answer:

sin^-1 (1/2) = 30°

Step-by-step explanation:

* Lets explain how to find the trigonometry functions from the unit circle

- The unit circle is the circle whose radius is 1 unit

- It intersects the four axes at:

# Positive part of x-axis at (1 , 0) and negative part at (-1 , 0)

# Positive part of y-axis at (0 , 1) and negative part at (0 , -1)

- The terminal of any angle intersect it at point (x , y) where x² + y² = 1

- If The angle between the terminal side and the x-axis is Ф , then

# The adjacent side of Ф = x

# The opposite side of the angle Ф = y

- In the problem the terminal side lies in the first quadrant

∴ all the trigonometry functions are positive

∵ sin Ф = opposite/hypotenuse

∵ The opposite = 1/2 and the hypotenuse is the terminal side = 1

∴ sin Ф = 1/2 ÷ 1 = 1/2

- To find Ф use the inverse function sin^-1 Ф

∵ sin Ф = 1/2

∴ Ф = sin^-1 (1/2)

∴ Ф = 30°

* sin^-1 (1/2) = 30°
