Question

Please help

Answer 1

(a) Using Sine Rule, 7/sin(30) = c/(sin90) --> c=14
By Pythagoras' Theorem, a = sqrt(14^2 - 7^2) = sqrt (196-49) = 12.124cm

(b) sin(30 deg) = 0.5000; cos(30 deg) = (sqrt3)/2 = 0.8660; tan(30deg) = 0.5774

(c) Try doing this by inputting the values into your calculator. Then upload your answers here for verification.
