In the diagram, ab is parallel to de. also, de is drawn such that the length of de is half the length of ab. if sin a = 0.5, then what is sin e?

a) 2
b) 1
c) 0.5
d) 0.25
e) 0.1

random answers will be reported!

C) 0.5

Step-by-step explanation:

Since DE is parallel to AB, angle FDE = ABF and  DEF = angle FAB

In fact, both triangles (ABF and DEF) are similar to each other because their interior angles are identical.

So, if sin(A) = 0.5, sin(E) = 0.5 too.

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:
