Step-by-step explanation:
128 - 20 * 25 / 5 + 11
= 128 - 100 + 11
= 39.
Since the 3 lengths of the triangle are given, one can use the Cosine law:
b^2 = a^2 + c^2 -2ac cos(B)
18^2 = 22.5^2 + 13.6^2 -2(22.5)(13.6) cos(B)
B = 53.12 deg
Using Sine law for C
18/(sin (53.12)) = 13.6/(sin ( C))
C = 37.19 deg

Answer:
33
Step-by-step explanation:
(24 + 3) + 3 + 3
(27) + 3 + 3 First solve what's in the parenthesis
30 + 3 Then work left to right
