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 .

Solve the system of equations using substitution.

Answer:

( $\frac{1}{3}$ , 3 )

Step-by-step explanation:

Given the 2 equations

y = 9x → (1)

6x - y = - 1 → (2)

Substitute y = 9x into (2)

6x - 9x = - 1, that is

- 3x = - 1 ( divide both sides by - 3 )

x = $\frac{1}{3}$

Substitute x = $\frac{1}{3}$ into (1) for corresponding value of y

y = 9 × $\frac{1}{3}$ = 3

Solution is ( $\frac{1}{3}$ , 3 )
