Correct answer is C
xo + 36o + 54o + 28o + 90o + 120o = 360o
x + 328o = 360o
x = 360o - 328o
x = 32o

Correct answer is D
x10 = 235
x10 = 2 x 51 + 3 x 50
= 10 + 3
= x10 = 13
Evaluate \(\int\)(cos4x + sin3x)dx
sin4x - cos3x + k
sin4x + cos3x + k
\(\frac{1}{4}\)sin4x - \(\frac{1}{3}\)cos3x + k
\(\frac{1}{4}\)sin4x + \(\frac{1}{3}\)cos3x + k
Correct answer is C
\(\int (\cos 4x + \sin 3x) \mathrm d x\)
= \(\frac{1}{4} \sin 4x - \frac{1}{3} \cos 3x + k\)
