cosx=-(5)/(13),xin [(pi )/(2),pi ]

Question

Answer 1

To solve the equation

in the interval

, we need to find the value of

that satisfies this equation.The cosine function is negative in the second quadrant, which corresponds to the interval

. Therefore, we can use the inverse cosine function to find the value of

.The inverse cosine function, denoted as

, is defined as the angle whose cosine is a given value. In this case, we have:

Using a calculator or a trigonometric table, we can find the value of

to be approximately

.Therefore, the solution to the equation

in the interval

is:
