Using the image as a reference, what is the csc of angle 90 - x?

Option (F)

Step-by-step explanation:

Cosec of an angle is the ratio of Hypotenuse and Opposite side.

From the figure attached,

ΔABC is a right triangle.

m∠A + m∠B + m∠C = 180°

m∠A + 90 + x = 180

m∠A = 180° - (90 + x)°

        = (90 - x)°

Now csc (90 - x)° =

                            =

                            =

                            = 1.67

Therefore, Option (F) will be the answer.

the answer is 13 cm

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
