An isosceles triangle has an angle of 70°. what are the possible values of the other two angles?​
IRINA_888 [86]

Answer:

55 and 55 or 70 and 40

Step-by-step explanation:

A triangle has 180o and an isosceles triangle has two angles that are the same. As 70 is less than half, we have a couple of possible solutions to this. So one possible solution is 70-55-55. So the other possible solution is 70-70-40.
