We know that

in the right triangle
sin x=opposite side angle x/hypotenuse
opposite side angle x=66 mm
hypotenuse=79 mm
so
sin x=66/79
x=arc sin (66/79)-------> x=56.66°-------> x=56.7°

the answer is
x=56.7°

What is the value of x in the parallelogram CDEF if top left corner is 104 degrees and bottom right corner is (2x+16) degrees?​
Travka [436]

Answer:

  x = 44

Step-by-step explanation:

Opposite angles in a parallelogram are congruent, so ...

  104 = 2x +16

  88 = 2x . . . . . . subtract 16

  44 = x . . . . . . . divide by 2

What is the slope of the line (-2,-6) and (2,2)
avanturin [10]

Answer:

slope = 2

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 2, - 6) and (x₂, y₂ ) = (2, 2)

m = \frac{2+6}{2+2} = \frac{8}{4} = 2
