Question

One angle of a triangle measures 40° and the other two angles are in the ratio 1:3. Find these angles.
​

Answer 1

Answer:

Angles are 35° and 105°

Step-by-step explanation:

let angles be x &3x.

Sum of angles of triangle =180

40°+x+4x =180°

40°+4x=180°

4x=180°-40°

4x=140°

x=140°\4

x=35°

3x=105°

Angles are 35° and 105°

Answer 2

Answer:

let the 1 angle =x

and 2 angle =3x

third angle =.40

then ,x+3x+40=180

4x +40=180

4x=140

x=140/4=35°
