Explanation

If a line intersects two coplanar lines, then the two internal angles on the coplanar lines are called corresponding angles.

Explanation

Let's consider the radius is r and therefore the Area will be πr².

Now the radius is increased by 4 times than the Area would be.

π(4r)² or the area would work to 16 times (4²=16).

Explanation

= (1+.1+.01+.001)

=1.111

Explanation

Area of the square = 49cm²

Side of square = X

Area of the square = X²

49= X²

X² =49

X=√49

X= 7

The side of the square =X=7cm

Explanation

For an angle in the first quadrant the point P has positive x and y coordinates.

Therefore: In Quadrant I, cos(θ) > 0, sin(θ) > 0 and tan(θ) > 0 (All positive). 

Explanation

Explanation

When cosθ = 90°, the value of cosθ is zero and so the work done is always zero.

Explanation

The logarithm base 10 is called the decimal or common logarithm

 commonly used in science and engineering.

Explanation

A rectangle is a four-sided shape with four right angles (90-degree angles).

There are two types of special rectangles including:

the square 

the Fibonacci rectangle.

Explanation

 the average of the data is also known as the arithmetic mean.
