The terminal side of an angle in standard position passes through P(15, –8). What is the value of sine theta? sine theta = fifte
Pavlova-9 [17]

The value of sine theta = negative eight-seventeenths ⇒ 2nd

Step-by-step explanation:

Let us revise the quadrant of an angle its terminal side passes through a given point

  • If the given point is (x , y), then the angle lies in the 1st quadrant
  • If the given point is (-x , y), then the angle lies in the 2nd quadrant
  • If the given point is (-x , -y), then the angle lies in the 3rd quadrant
  • If the given point is (x , -y), then the angle lies in the 4th quadrant

∵ The terminal side of angle Ф passes through P (15 , -8)

∵ x = 15 and y = -8

- P is (x , -y), then the angle Ф lies in the 4th quadrant

∵ The terminal side of angle Ф is the hypotenuse of a right

   triangle whose horizontal leg is 15 units and vertical leg

   is -8 units

- Use Pythagoras Theorem to find the length of the hypotenuse

∴ Hypotenuse = \sqrt{(15)^{2}+(-8)^{2}}=17 units

∵ sinФ = \frac{opposite}{hypotenuse}

∵ The side opposite to Ф is -8

∵ The hypotenuse is 17

∴ sinФ = \frac{-8}{17}

The value of sine theta = negative eight-seventeenths

Answer:

-\frac{65}{28} or -2\frac{9}{28}

Step-by-step explanation:

Add all fractions:

-1\frac{3}{4} + -\frac{1}{28} + -\frac{15}{28} = -\frac{65}{28}

Simplify if needed:

-\frac{65}{28} = -2\frac{9}{28}
