Question

if one of a triangle is 80° and the other two angles are in the ratio 3:7 . find the angles​

Answer 1

Answer:

ab and cd or 80 cm ki arc and middel me 7 or upper me 3

Answer 2

Answer:

Let the <B be 3x

<C be 7x

using the angle sum property,

<A+<B+<C = 180 degree

80+3x+7x = 180 degree

80+10x = 180 degree

10x = 180-80 = 100 degree

10x = 100 degree

x = 100/10 = 10 degree

So, the second angle is 3x = 10*3 = 30

the third angle is 7x = 10*7 = 70
