Answer:
Part 3)


Part 4) 
Step-by-step explanation:
Part 3)
<em>step 1</em>
Find the value of x
In the right triangle of the figure we know that
The cosine of angle of 30 degrees is equal to the adjacent side to angle of 30 degrees divide by the hypotenuse
so

and remember that

substitute

Simplify

<em>step 2</em>
Find the value of y
In the right triangle of the figure we know that
The sine of angle of 30 degrees is equal to the opposite side to angle of 30 degrees divide by the hypotenuse
so

and remember that

substitute


Part 4) Find the value of x
Applying the Pythagoras Theorem

Simplify

If we know that two sets of corresponding angles and the corresponding included sides are congruent in two triangles, what can we say about the triangles?
