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 .

You have to use trigonometry.

To find the angle which is the fartest from the known angle, you use the SINE.

So 6*sin(50°) = 6*0,766 = 6*0,8 = 4,8 cm

Answer C

Can someone help me on this math problem.
nekit [7.7K]

In the rhombus, the diagonals are perpendicular.

We know, the sum of the measures of the triangle is equal 180°.

Therefore we have the equation:

(2x-15)+3x+90=180

2x-15+3x+90=180        <em>combine like terms</em>

(2x+3x)+(-15+90)=180

5x+75=180        <em>subtract 75 from both sides</em>

5x=105              <em>divide both sides by 5</em>

\boxed{x=21}

<h3>Answer: x = 21°</h3>
