Answer 1

Answer:

7 it is a correct answer please mark me brainlest and follow me............

Answer 2

Answer:

Let the required angle be x

Complement = 90° - x

Supplement = 180° - x

❍ According to Question now,

➝ 7(90° - x) = 3(180° - x) - 10

➝ 630° - 7x = 540° - 3x - 10

➝ 630 - 540 + 10 = -3x + 7x

➝ 100° = 4x

➝ x = 100/4

➝ x = 25°
