In a triangle, if side a = 23, side b = 11 and angle A = 122 degrees, find the value of angle B to the nearest degree.
find B using law of sines:
sinB/b = sinA/a
Find the value of angle A in the triangle where a = 8, b = 6 and c = 7 to the nearest degree.
find A using the law of cosines:
a^2 = b^2 + c^2 - 2bc cosA
Find the area, to the nearest whole number, of a triangle where a = 7 ft, b = 9.3 ft and angle C = 86 degrees.
area = 1/2 ab sinC
Find the area of the triangle, to the nearest whole number, with a = 5, b = 6 and c = 9.
use Heron's formula (much work), or find A using the law of cosines
and then the area is 1/2 bc sinA
