Question

In ∆IJK, i= 340 cm < I =120° and

Answer 1

ok

Find K

K/sin 1 = 340/sin120

k = 340 sin 1 / sin120

K = 340 *(0.020)

K = 6.85 cm

Find J

J/sin 59 = 340/sin120

J = 340 sin59/sin120

J = 340 *(0.98977)

J = 336.5 cm

Area = base x height / 2

height = 6.85

Area = 6.85 x 336.5 / 2

Area = 2305.025 / 2

Area = 1152.5 cm^2
