The vertex angle of an isosceles triangle is 2/3 of the external angle adjacent to it. Calculate the amplitudes of its internal and external angles.

1/8 3/16 3/4

step-by-step explanation:

you put them as all the same denominator and multiply

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.

i think its a.

hope this

what's the question here?
