Question

If csc x° = five fourths, what is the value of b? triangle LMN in which angle M measures 90 degrees, angle L measures x degrees, LN measures 22.5 units, and NM measures 3b units b = 4 b = 5 b = 6 b = 7

Answer 1

Answer:

b=6

Step-by-step explanation:

csc(x°) = LN/NM

5/4 = 22.5/(3b)

b = 22.5·4/(5·3)

b  = 6
