What is the approximate value of X? Round to the nearest tenth.
pychu [463]

Answer

Find out the value of x.

To prove

By using the trignometric identity

sin\theta = \frac{Perpendicular}{Hypotenuse}

 As given in the diagram.

\theta = 50 ^{\circ}

Perpendicular = x

Hypotenuse =  6

Put in the above identity

sin\ 50^{\circ} = \frac{x}{6}

sin\ 50^{\circ} = 0.77\ (Approx)

Put in the above

x = 6\times 0.77

x =  4.6 cm (Approx)

Therefore Option (c) is correct .

Please answer and use statement reason
masha68 [24]

Answer:

x = 15

Step-by-step explanation:

FD and AC are parallel because both are perpendicular to EB. Angle EDF and Angle DCA are congruent because they are corresponding angles. The measure of Angle DCA is also 3x because congruent angles have the same measure.

Now consider Triangle ACD. Because the sum of all three measures of the angles in a triangle add up to 180°.

x + 8x + 3x = 180°

12x = 180°

12x/12 = 180/12

x = 15
