Answer:

Perimeter = 54.6 cm

Area = 173 cm²

sin 30 = x/20

x = 10

cos 30 = y /20

y = 17.3

perimeter = 10 + 17.3 + 10 + 17.3 = 54.6 cm

area = 10 * 17.3 = 173 cm²

QF Q8.) Solve the triangle.
Anuta_ua [19.1K]
A triangle solver tells you
  C = 85°
  b ≈ 8.4
  c ≈ 10.4

From the sum of angles of a triangle, 
  C = 180° -42° -53° = 85°

From the law of sines
  b = sin(53°)/sin(42°)*7 ≈ 8.355
  c = sin(85°)/sin(42°)*7 ≈ 10.422
