GIVEN :–
• Difference of two angles is 90°.
• One angle is ⅓ of second angle.
TO FIND :–
• Angles = ?
SOLUTION :–
• Let the the first angle is 'x' , then second angle is 'x/3'.
• According to the question –
• Other angle –
• Hence , First angle is 135° and second angle is 45°.
_________________________________
VERIFICATION :–
• Difference between angles = 90°
=> 135° - 45° = 90°
=> 90° = 90°
[ Hence Proved ]

♣GIVEN :–
- Difference between two angles = 90°
- One of the number is 1/3 of the other number
♣TO FIND :–
- The measure of the angles
♣SOLUTION :–
Let one of the angles be x °
ஃ The other one must be = (1/3 × x)° = (x/3)°
卐 By the problem :-
→ x + x/3 = 90 [It is stated that the difference of the angles is 90°]
→ 3x - x/3 = 90
→ 2x/3 = 90
→ 2x = 90 × 3
→ x = 270/2
➠ x = 135
____________________________
- The first angle = x° = 135°
- The other angle = (x/3)° = (135/3)° = 45°
____________________________
★ Let's Verify Our Result Now :–
- x + x/3 = 90
⟹ 135 - (135/3) = 90
⟹ 135 - 45 = 90
⟹ 90 = 90
LHS = RHS
HENCE VERIFIED!!
