In a right-angled triangle ABC, angle C = 90 degrees, AC = 30 cm Find: a) Side AB

In a right-angled triangle ABC, angle C = 90 degrees, AC = 30 cm Find: a) Side AB b) Height CD, drawn to the hypotenuse

There is not enough data in the condition for a solution. Let’s look at the solutions to the problem.

In order to draw up the equation of a circle with a center at the origin and a radius equal to b cm, we start by recalling the formula for a circle.

In general terms, the formula can be written as:

(x – x0) ^ 2 + (y – y0) ^ 2 = R ^ 2.

In the formula (x0; y0), the center of the circle, and R is its radius.

We know that the center of the circle is the origin of coordinates, that is, O has coordinates (0; 0), and the radius of the circle is R = b.

That is, x0 = 0; y0 = 0.

We get the equation:

(x – 0) ^ 2 + (y – 0) ^ 2 = b ^ 2;

x ^ 2 + y ^ 2 = b ^ 2.
