Yanka [14]3 years ago
8 0

Answer:

D)  sin(\frac{4\pi }{3} ) = sin(\pi +\frac{\pi }{3} ) = -sin\frac{\pi }{3}

Step-by-step explanation:

A)

sin(\frac{2\pi }{3} ) = sin ( \pi - \frac{\pi }{3} ) = sin\frac{\pi }{3}

B)

cos (\frac{\pi }{6} ) = cos ( \frac{\pi }{2} - \frac{\pi }{3} ) = sin(\frac{\pi }{3})

C)

cos (\frac{11\pi }{6} ) = cos ( \frac{3\pi }{2} + \frac{\pi }{3} ) = sin(\frac{\pi }{3})

D)

 sin(\frac{4\pi }{3} ) = sin(\pi +\frac{\pi }{3} ) = -sin\frac{\pi }{3}

pentagon [3]

Answer:

D

Step-by-step explanation:

Triangle BDC is a right triangle (If you dont understand I can explain in depth).  Since it's a right triangle, we can use the pythagorean theorem to find the length of BD.  The pythagorean theorem states that the length of the smaller legs squared = the longest side squared.  So we can set up the equation 9^{2}+x^{2}=15^{2} where x is the length of the missing side (BD).  If we were to solve for x, (I think you should know how to do this but if not I can explain), you get 12

In the diagram below, RSTU is a rectangle, and the two shaded regions are squares.
sdas [7]

Answer:

length PQ = 8.9 m  

Step-by-step explanation:

The picture below completes the question you  asked. From the picture above RSTU is a rectangle . The two shaded square has a length of sides 8 m and 4 m respectively. The legs of the triangle is the sides of the 2 squares. Therefore, the triangle is a right angle triangle. The adjacent side is 4 m while the opposite side is 8 m.

Using Pythagoras theorem the hypotenuse of the triangle can be calculated below.

Pythagoras theorem

c² = a² + b² Therefore,

c² = 4² + 8²

c² = 16 + 64

c² = 80

square root both sides

c = √80

c = 8.94427191

c ≈ 8.9 m

length PQ = 8.9 m
