The required value of b = 6 for a triangle LNM. Option C is correct.
Given, CSC x° = 5/4 value of b is to be determined.
What is the triangle?
The triangle is a geometric shape that consists of3 sides and the sum of the interior angle should not greater than 180°
csc(x°) = hypotenuse/ perpendicular = LN/NM
5/4 = 22.5/3b (NM = 3b)
b = (22.5*4)/(5*3)
b = 90/15
b = 6 and
NM = 3*6 = 18
Thus, the required value of b = 6 for a triangle LNM.
