Answer:

10.5 inch

Step-by-step explanation:

As we know that the angle rotated in one complete rotation is 360 degree.

The distance traveled in one complete rotation is circumference of the circle.

So, in 360 degree, the distance covered = 2 x 3.14 x Radius

                                                                    = 2 x 3.14 x 4 = 25.12 inch

In 1 degree, the distance covered = 25.12 / 360 inch

In 150 degree, the distance covered = 25.12 x 150 / 360 = 10.5 inch

Answer:

<h3><u>Firs</u><u>t</u><u> </u><u>q</u><u>uestion</u></h3>

To find ? we use sine

sin ∅ = opposite / hypotenuse

From the question

The hypotenuse is 50

The opposite is 25

So we have

sin ? = 25 / 50

sin ? = 1/2

? = sin-¹ 1/2

<h2>? = 30°</h2>

<h3><u>Sec</u><u>ond</u><u> </u><u>q</u><u>uestion</u></h3>

To find ? we use tan

tan ∅ = opposite / adjacent

From the question

the opposite is 8

the adjacent is 33

So we have

tan ? = 8/33

? = tan-¹ 8/33

? = 13.62

<h3>? = 14° to the nearest degree</h3>

Hope this helps you
