Answer 1

Answer:

Mark as brainliest answer.

Step-by-step explanation:

→ Let one angle be 3x

→ Other angle be 4x

→ A.T.Q

→ 3x + 4x = 180

→ 7x = 180

→ x = 180/7

→ x = 25.7

→ Now put value of x.

→ 3x = 3(25.7) = 77.1°

→ 4x = 4(25.7) = 102.8°

→ So, The angles are 77.1°  and 102.8°

Answer 2

Answer:

Correct Question :-

• The two supplementary angles are in the ratio of 3 : 4. Find the angles.

Given :-

• The two supplementary angles and in the ratio of 3 : 4.

To Find :-

• What are the angles.

Solution :-

Let, the first angles be 3x

And, the second angles will be 4x

As we know that,

✯ Sum of two angles = 180° ✯

According to the question by using the formula we get,

⇒ $\sf 3x + 4x =\: 180^{\circ}$

⇒ $\sf 7x =\: 180^{\circ}$

⇒ $\sf x =\: \dfrac{\cancel{180^{\circ}}}{\cancel{7}}$

➠ $\sf\bold{\red{x =\: 25.7^{\circ}}}$

Hence, the required angles are,

✧ First angles = 3x = 3(25.7°) = 77.1°

✧ Second angles = 4x = 2(25.7°) = 102.8°

$\therefore$ The angles are 77.1° and 102.8°.
