Question

In an isosceles triangle the base angles are equal, the angle at vertex is 30°. Find the base angles.
​

Answer 1

Answer:

70

Step-by-step explanation:

Since the sum of all angels of a triangles

=180

Let the base angles be 'x'

Therefore,

x+x+40=180

2x=180-40

2x=140

X= 140/2

x = 70

Hence the base angles of the triangle are 70,
