Please help ASAP ASAP please
Serhud [2]

Answer:

PT = 1.5 , VT = 1.5√3

Step-by-step explanation:

Given

PV = 3

With reference angle 60°

hypotenuse (h) = 3

perpendicular (p) = ?

sin 60° = p/h

√3 / 2 = p / 3

p = √3 * 3 / 2

p = 1.5√3

With reference angle 30°

hypotenuse (h) = 3

perpendicular (p) = ?

sin 30° = p/h

1/2 = p/ 3

p = 1.5

Hope it will help :)❤
