Answer:

kindly see the answer below...

Step-by-step explanation:

Here,

we know that a triangle has three angles...

as like this an isosceles triangle has

two \: equal \: angles \: and \: one \: vertex \: angle

and \: sum \: of \: the \: angles \: of \: a \: triangle = 180

then,

let the vortex angle be X =40°

and the equal angles be y...

therefore,

x + y + y = 180

or \: 2y = 180 - 40

or \: y =  \frac{140}{2}

or \: y = 70

so, the measures of the angles of the isosceles triangle is

40° , 70° and 70°...

thanks a lot...
