Question

In right triangle ABC, mA = 90°, cos

Answer 1

The value of x in the triangle is 0.21

How to determine the value of x?

The given parameters are:

mA = 90°

cos(B) = 7x - 0.55

sin (C) = x + 0.71

Since the angle is a right triangle, then

C + B = 90

In a right triangle;

If C + B = 90, then

sin(C) = cos(B)

So, we have:

7x - 0.55 = x + 0.71

Evaluate the like terms

6x = 1.26

Divide both sides by 6

x = 0.21

Hence, the value of x in the triangle is 0.21
