Answer:

Step-by-step explanation:

9) to determine x, we would apply the sine rule which is expressed as

a/SinA = b/ SinB = c/SinC

Therefore,

12/Sin95 = 8/Sinxx

Cross multiplying, it becomes

12Sinx = 8Sin95 = 8 × 0.9962

Sinx = 7.9696/12 = 0.6641

x = Sin^-1(0.6641)

x = 41.61°

10) we would apply the cosine rule. It is expressed as

a² = b² + c² - 2abcosA

Therefore,

x² = 6² + 8² - 2 × 6 × 8 × Cos 100

x² = 36+ 64 - 96 × - 0.1736

x² = 100 + 16.6656 = 116.6656

x = √116.6656

x = 10.8

Answer:

The answer to your question is below

Step-by-step explanation:

Number 9.

To find x use the law of sines

                   sin x / 8 = sin 95 / 12

Solve for sin x

                   sin x = 8 sin 95 / 12

                   sin x = 0.664

                        x = 41.6°

Number 10

To find x use law of cosines

                    x² = 6² + 8² - 2(6)(8)cos100

                    x² = 36 + 64 - 96(-0.174)

                    x² = 100 + 16.67

                    x² = 116.67

                   x = 10.80

1/5x1/2=1/10

1/5 because there are 5 flavors.
1/2 because there are 2 kinds of pies.
So the answer is 1/10.

Hope this helps.

Help anyone pleaseeee
AlexFokin [52]

Answer:

36 <127

(36,127°)

36 [ cos (127) + i sin (127)]

Step-by-step explanation:

w1 = 2 < 95

w2 = 18 < 32


w1 * w2

We multiply the magnitude and add the angles

w1 * w2 = 2*18 < (95+32)

            =36 < 127

             36 [ cos (127) + i sin (127)]
