Find the measure of C to the nearest degree.
Alisiya [41]

Let the ∠C be : θ

From the figure, We can see that the Side which is opposite to angle θ is measuring 7 units

Also, We can notice that Hypotenuse is 11 units

As we are dealing with opposite and hypotenuse, we can clearly use Sinθ to find out the angle θ

We know that :

\bigstar \ \ \boxed{\sf{Sin\theta = \dfrac{Opposite \ Side}{Hypotenuse}}}

\implies \sf{Sin\theta = \dfrac{7}{11}}

\implies \sf{\theta = Sin^{-1}\bigg(\dfrac{7}{11}\bigg)}

\implies \sf{\theta = 39.52^{\circ}}

<u>Answer</u> : The measure of ∠C to the nearest degree is 38°

5x−4 = 3x +8<br> i need the steps on how to find x<br> plz, i got a 0 the first time i did it
svetoff [14.1K]

Answer:

5x − 4 = 3x + 8

5x - 4 <em>+ 4</em> = 3x + 8 <em>+ 4</em>

5x = 3x + 12

5x <em>- 3x</em> = 3x + 12 <em>- 3x</em>

2x = 12

2x <em>/ 2</em> = 12 <em>/ 2</em>

x = 6

If the discriminant is 22, then the roots of the quadratic equation are ________________.
Allisa [31]

Since the discriminant given has a value that is greater than zero, hence  the roots of the quadratic equation are real and distinct.

<h3>Discriminant of a quadratic equation</h3>

Quadratic equation is an equation that has a leading degree of 2. The discriminant is used to determine the nature of the equation

If D > 0 , the roots of the quadratic equation are real and distinct.

If D < 0 , the roots of the quadratic equation are complex

Since the discriminant given has a value that is greater than zero, hence  the roots of the quadratic equation are real and distinct.
