<u>Answer: D) 2a - 5b</u>
Answer:
60
Step-by-step explanation:
The first step is to find the value of
. X is equal to:
. Since
is equal to
, the greatest angle measure in the triangle is:
which gives 60.

answer
C. 108 degrees
3)
cos (3</span>π/4) = -√2 / 2
sin ((3π/4) = √2 / 2
cos (3π/4) and sin ((3π/4) = -√2 / 2 * √2 / 2

Answer:
that would be 67.2
Step-by-step explanation:
I hope this helps!
C = 43.6 degrees (1 dp)
You cannot find C using the sine law without knowing one of the other angles.
In your previous question I showed you that A = 71.5
sin(C)/16 = sin(71.5...)/22
sin(C) = 16 x sin(71.5...)/22 = 0.68977...
C = sin^-1(0.68969) = 43.6 degrees
