1. Rectangle

2. 376.8 cm

4. –4 and 4

Step-by-step explanation:

A square is always a rectangle.

If a wheel has a radius of 15 cm, it would travel approximately 376.8 cm per 4 revolutions.

If the diameter of a circular garden is 22 feet, the approximate area of the garden is 379.94 square feet.

The solutions to the equation y2 – 1 = 15 is –4 and 4.

Help please! will give brainliest! and can please explain.
storchak [24]

Answer: 150

We know that cos Ф = sin (90 - Ф)

If Ф = 150, then:

cos 150 = sin (150 - 90)

cos 150 = sin 60

Using the equation they gave us:

cos 150 = sin ( \frac{150}{3} - 10)

cos 150 = sin 60
