Question

Anyone want to answer the number for X???????

Answer 1

Answer:

$\frac{\sqrt{10} }{2}$

Step-by-step explanation:

Using cosine (since that is adjacent over hypotenuse), cos(60)=1/2 so your answer is hypotenuse*1/2=$\sqrt{10}*\frac{1}{2}=\frac{\sqrt{10} }{2}$

Answer 2

Answer:

$x = \frac{\sqrt{10} }{2}$

Step-by-step explanation:

Using Pythagoras Theorem:

The triangle has hypotenuse of √10 , opposite side x, angle 30°

Using the formula:

                                   $sin(A) = \frac{opposite}{hypotenuse}$

                                   $sin(30)= \frac{x}{\sqrt{10} }$

                                    $x = sin(30) * \sqrt{10}$

                                    $x = \frac{\sqrt{10} }{2}$
