Question

Calculate the perimeter of triangle ABC

Side BC = y
Side AC = x
Side AB = 6

Angle B = 63
Angle C = 65
Angle A = 52

Answer 1

Set your calculator to degree mode.

6/sin(65°) = x/sin(63°)

x = 6sin(63°)/sin(65°) = about 5.899

6/sin(65°) = y/sin(52°)

y = 6sin(52°)/sin(65°) = about 5.217

Perimeter = 6 + x + y = about 17.116
