Answer:
pls see the explanation
Step-by-step explanation:
Let the unknown angles be 3x and 5x
=》60°+ 3x +5x=180°
=》180°-60°=3x+5x
=》120°=8x
=》x=120/8
=》x= 15°
therefore the angles are
3x=45°
5x=75°

Answer:
Step-by-step explanation:
The first angle is 60°
Let the other two angles be A in ratio 3:5
⇒ 3A and 5A
The sum of three angles in a triangle = 180°
⇒ 3A + 5A + 60° = 180°
⇒ 8A = 180° - 60°
⇒ 8A = 120°
⇒ A = 120° / 8
⇒ A = 15°
The two angles are 3A and 5A = 3x15° and 5x15°
= 45° and 75°
