Question

. The sum of two adjacent angles is 140. If
one angle is thrice that of the other. Find
the two angles.​

Answer 1

Answer:

Let angle 1 be x

Other angle = 3 x

Sum of both angles = 140 °

3x+x =140°

4x = 140°

x = 140/4 = 35 °

x = 35°

Other angle = 3x = 3×35° = 105°

Answer 2

Answer :

The angles are :- 35° and 105°

Step-by-step explanation :

To Find :

• The measure of the two angles ....(?)

Solution :

Let the first angle be x and the second angle be 3x

Given that,

⟹ x + 3x = 140

⟹ 4x = 140

⟹ x = 140 / 4

⟹ x = 35

The value of x is 35

Now, the angles are :-

First angle ( x )

» 35°

Second angle ( 3x )

» 3 × 35

» 105°

Now, Verification

Given that,

⟹ x + 3x = 140°

By putting the values,

⟹ 35 + 105 = 140

⟹ 140 = 140

L.H.S = R.H.S

Hence, Verified !
