Answer 1

Answer:

ans)In a triangle,

sum of all the angles=180 degrees measure of given angle=125 degree

measure of the angle remaining =180-125 degrees

=55 degrees

Ratio of the remaining angles=2:3

Sum of the ratio terms=2+3=5

Measure of first angle=2/5*55

=22 degrees

Measure of second angle=3/5*55

=33 degrees

Answer 2

Answer:

The angles of the triangle are 55° , 50° and 70°

Step-by-step explanation:

Let the angles of the triangle be ∠a, ∠b and ∠c .

Exterior angle = 125° = ∠d

∠d + ∠a = 180°  (linear pair)

125 + ∠a = 180

∴ ∠a = 55°

By triangle sum property

∠a + ∠b+ ∠c = 180°

55 + 2x + 3x = 180°    

∵ The ratio of the opposite angles is 2:3

∴ 5x = 125

     x = 125/5

     x = 25

∠b = 2x = 2 × 25 = 50

∠c = 3x = 3 × 25 = 75

∴ The angles of the triangle are 55° , 50° and 70° .
