Can someone help on a construction of a tangent to a circle please, need pictures if possible
Anit [1.1K]

Wassup

Steps:

1. Draw a line connecting the point to the center of the rectangle

2. Then construct a perpendicular bisector to the line drawn in step 1

3. Place the compass on the midpoint of the line, adjust its length to reach the end point, and draw an arc across the circle

4. Where the arc crosses the circle will be the tangent points. So connect the endpoint to the tangent point

Hope the picture helps you too

Part 1 - Application
egoroff_w [7]

The measure of the central angle is 89.95 degree or 1.57 radians if the radius of the circle is 7 cm.

<h3>What is a circle?</h3>

It is described as a set of points, where each point is at the same distance from a fixed point (called the centre of a circle)

We have a  length of an arc of a circle of radius 7 is approximately 10.99 cm.

The radius r = 7 cm

The arc length l = 10.99 cm

We know,

l = rθ

θ is the central angle.

θ = l/r  = 10.99/7 = 1.57 radians

To convert 1.57 radians into the degree multiply it by 180/π

θ = 89.95 degree

Thus, the measure of the central angle is 89.95 degree or 1.57 radians if the radius of the circle is 7 cm.

How to calculate angle BCE?
Olenka [21]

Answer:

75.3 degrees ( to nearest tenth).

Step-by-step explanation:

If we take a section  through the plane BCHE we get a rectangle.

BC = 2 cm and BE  = √(7^2 + 3^2). ( By the pythagoras theorem).

tan < BCE = √(7^2 + 3^2) / 2.

So the m < BCE = 75.3 degrees.
