PLEASE HELP !! c = 49 cm, a = 41°. Find B in degrees. Round to 2 decimal places.
1 answer:
Answer:
49.03 degrees
Step-by-step explanation:
c = 49, = 41
We can solve for if we first find b.
Remember: SOH CAH TOA
Cosine = Adj/Hypotenuse
So, Cos (41) = b/49
49 x (Cos 41) = b
49 x .755 = b
b = 36.99
sin = Opp/Hyp = b/49 = 36.99/49 = .755
β = inverse sin (.755) = 49.03° (Inverse sin is designated by sin⁻¹ on your calculator)

In every triangle, the largest side, is opposite the largest angle.
Also, the smallest side, is opposite the smallest angle.
a.
so 
,
because RQ is opposite angle P, the largest,
PR is opposite angle Q , the middle
and PQ is opposite angle R, the smallest.
Greatest side: RQ
b. The sum of the measures of the interior angles of any triangle is 180°,
so
thus, m(C) is the largest angle. This means the largest side is the side AB.
