If my initial angle is 30 degrees, what is the negative coterminal angle?​

Answers

Answer:

Step-by-step explanation:

Coterminal angles are angles in standard position (angles with the initial side on the positive x -axis) that have a common terminal side. For example 30° , −330° and 390° are all coterminal.

Answer:

-330°

Step-by-step explanation:

Coterminal angles have a difference of 360° or multiples of 360°.

Negative coterminal angle with 30° is:

30° - 360° = -330°

Answer: x is 36 degrees

Step-by-step explanation:

To solve this triangle, we can use sin -1 x = 14 / 24. This gives us 35.69 degrees, but in your answer choices you only get integers. We can round this up to 36 degrees to get the answer.

Answer:

36°

Step-by-step explanation:

sinx=14/24

x=[tex]sin^{-1} (\frac{14}{24})[/tex]

Answer:

uiptyftyfkghfcytfghvchjcghcfgcjvbcfg

Step-by-step explanation:

Answer:

2nd option

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )

Here A = 75, b = b , h = b - 10, then

[tex]\frac{1}{2}[/tex] b(b - 10) = 75 ( multiply both sides by 2 to clear the fraction )

b(b - h) = 150 ← option 2
