Question

Find ∠C and hence classify each triangle according to:

Answer 1

Answer:

a) 0

b) scalene and obtuse

Step-by-step explanation:

∠A = 20

∠B = 60

∠C = 180 - 20 - 60 = 100 (obtuse)

Since none of the angles are equal, no sides are equal either

So, it's a scalene triangle

Since one angle is obtuse, it's an obtuse triangle
