Question

Suppose <A is one of the acute angles formed by the line x+2y=6 and the x axis. What is the approximate measure of <A to the nearest degree of <A?

Answer 1

triangle abc has sides a=11 b=13 and c=15. find the sum of the angles supplementary to angles a, b, c

Answer 2

1. x + 2y = 6.

Slope = -a/b = -1/2 = -0.50.
tanA = -0.50.
A = 27o.
