Question

Can a triangle have sides with the given lengths? Explain. a = 6 yd, b = 9 yd, c = 11 yd

Answer 1

Answer:

Step-by-step explanation:

Use the cosine rule and see if the numbers hold true. a^2 = b^2 + c^2 - (2bc (cos x))

By substituting in our values I get that cos x = 0.838... which is possible. If cos x would equal 1.5, the there is no solution and the triangle would not be possible.
