Find the value of x. write your answer in simplest radical form

BartSMP [9]

Answer:

<h2> $x = 4 \sqrt{2}$ </h2>

Step-by-step explanation:

To find the value of x we can use either sine or cosine

Using cosine we have

<h3> $\cos(\theta) = \frac{adjacent}{hypotenuse}$ </h3>

From the question

x is the hypotenuse

4 is the adjacent

We have

<h3> $\cos45= \frac{4}{x} \\ x \cos45 = 4 \\ x = \frac{4}{ \cos(45) }$ </h3>

We have the final answer as

<h3> $x = 4 \sqrt{2}$ </h3>

Hope this helps you

The kinetic energy (in joules ) of a moving object can be calculated from the expression 1/2mv to the second power, where m is t

yulyashka [42]

E = 1/2 m v^2

E = 1/2 (0.145) (40)^2

E = 0.0725 x 1600

E = 116 kg m^2/s^2

1 joule = 1 kg m^2/s^2

so here E in joules is 116 joules

so E = 116 joules

Claire says that she can draw an obtuse equilateral triangle. Is she correct? Explain.

notka56 [123]

No, because an equilateral triangle is also equiangular so all sides must be 60° (60+60+60=180) and an obtuse angle is more than 90° so the triangle would not be equilateral.
