Answer:

the third angle is 70 degrees

Step-by-step explanation:

an isosceles triangle has two equal angles and one other with a different angle value.

All angles add up to 180 degrees

therefore we can create the equation

180 = 55 + 55 + x

NB : x is the value of the third angle

180 = 110 + x

x = 180 - 110

x = 70

the third angle is 70 degrees

Step-by-step explanation:

Equal sides of the triangle= 55

Let the other angle be x,

Therefore, by the angle sum property, we get,

=> 55 + 55 + x = 180

=> 110 + x = 180

=>x = 180 - 110

=> x = 70

Therefore, the other angle = 70
