Question

1. In a A ABC,
2. If the angles of a triangle are in the ratio 1:2:3, determine three angles.
1
X - 10
Find the value of x.
3. The angles of a triangle are (x – 40)°, (x – 20) and
2
lo are equal and the third angle is greater than each of those​

Answer 1

Answer:

2.

given,

angles are in the ratio 1:2:3

let,angles be x.

the sum of all angles in a triangle is 180.

then,

1x+2x+3x=180,

6x=180,

x=180/6

x=30.

then angles

1x=1×30=30

2x=2×30=60

3x=3×30=90

therefore three angles=30,60,90
