Here, “p” is a numerator and “q” is a denominator. The examples of rational numbers are 6/5, 10/7, and so on. The rational number is represented using the letter “Q”. Like real numbers, the arithmetic operations, such as addition, subtraction, multiplication, and division are applicable to the rational numbers.

Two sides of a triangle are 7 m 7 m and 12 m 12 m in length and the angle between them is increasing at a rate of 0.06 rad/s 0.0

Answer:

1.26 m^2 / s.

Step-by-step explanation:

The area A of the triangle = 1/2*7*12 sin x = 42 sin x where x is the angle between the lines.

Relation between the rates is

dA/dt + dA/dx * dx/dt

We are given that dx /dt = 0.06 rad/s.

A = 42 sin x

dA/dx = 42 cos x
