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:

so 40+1x+3x=180

180 because sum of all angles in triangle is 180

40+4x=180

4x=140

x=140/4

x=35

Answer 2

Answer:

35° and 105°

Step-by-step explanation:

180-40=140°

140×1/4=35°

140×3/4=105°
