Find the three trigonometric..pls help due very soon

Answer:

sin 0 = 24/25

cos 0 = 7/25

tan 0 = 24/7

Step-by-step explanation:

hey there!

sine = opposite divided by hypotenuse

the opposite of angle 0 is 24 and the hypotenuse is 25 so sin 0 = 24/25

cosine = adjacent divided by hypotenuse

the adjacent of 0 is 7 and the hypotenuse is 25 so cos 0 = 7/25

Tangent.= opposite divided by adjacent

the opposite of 0 is 24 and the hypotenuse is 7 so tan 0 = 24/7

Write the verbal statement as an equation, using x for the variable.
viktelen [127]

Complete question:

<em>Write the verbal statement as an equation using x as a variable. Then solve. 2 more than 3 times a number is 17. </em>

<em />

The required expression is 3x + 2 = 17 and the value of x is 5

Let the unknown number be x

  • 3 times a number is expressed as 3x
  • 2 more than3 times the number is 3x + 2

If the result is equivalent to 17, the required expression will be 3x + 2 = 17

Solve the resulting expression:

3x + 2 = 17

3x = 17 - 2

3x = 15

x = 15/3

x = 5

Hence the required expression is 3x + 2 = 17 and the value of x is 5
