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
