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 :)❤

Which of the following best describes the relationship between (x + 1) and the polynomial x2 - x - 2?
Viefleur [7K]

Answer:

C

Step-by-step explanation:

to factor x² - x - 2

consider the factors of the constant term which sum to give the coefficient of the x-term.

the factors are - 2 and + 1 since - 2 × 1 = - 2 and - 2 + 1 = - 1

x² - x - 2 = (x - 2)(x + 1), hence (x + 1) is a factor
