Question

Determine whether the given sides and angle will define no triangle, one triangle or two triangles.

Answer 1

Answer:

a) 1 triangle

b) 2 triangles

c) no triangle

Step-by-step explanation:

a/sinA = b/sinB

a) 2/sin30 = 4/sinB

sinB = 1

B = 90

b) 4/sin40 = 6/sinB

sinB = 0.9641814145

B = 74.6, 105.4

c) 7/sin70 = 8/sinB

sinB = 1.073934424
