Find the sine, cosine, and tangent of 45 degrees.

frosja888 [35]

Answer:

The correct answer is option C.

Sin 45 degrees = square root of 2 divided by 2, cos 45 degrees = square root of 2 divided by 2, tan 45 degrees = 1

Step-by-step explanation:

The sin cos tan table used to calculate values of the ratios for different angles can be used for the values.

The table is easily available on the internet.

WE can use a a right-angles isosceles triangle to find the exact values for the angle 45.

The equal sides have length 1. So the thirs side using the pythagoras theorem will be √2.

Sin 45 = √2/2

Cos 45 = √2/2

and

Tan 45 = 1

So the correct option is C.

A circle with radius of \greenD{3\,\text{cm}}3cmstart color #1fab54, 3, start text, c, m, end text, end color #1fab54 sits insid

Zolol [24]

Answer:

The area of the shaded region is 125.664 square centimetre

Step-by-step explanation:

Area of the shaded region = area of the circle with radius 7 cm - area of the circle with radius 3 cm----------------(1)

Step 1: Finding the area of the circle with radius 7 cm

Area of the circle A = $\pi r^2$

On substituting the value of the radius, we get

Area of the circle A = $\pi(7)^2$

Area of the circle A = $49 \pi$ square centimetre----------------(2)

Step 2: Finding the area of the circle with radius 3 cm

Area of the circle a = $\pi r^2$

On substituting the value of the radius, we get

Area of the circle a = $\pi (3)^2$

Area of the circle a = $9 \pi$ square centimetre ----------------(3)

Step 3: Finding the area of the shaded region

Area of the shaded region = $49 \pi - 9\pi$

= $40 \pi$

= 125.664 square centimetre
