Question

two supplemntary angle are in ratio 7:8 find the angle​

Answer 1

Answer:

Step-by-step explanation:

Let two complementary angles are lx and 8x

∴ 7x + 8x = 90°

⇒ 15x = 90°

⇒ x = \frac { 90 }{ 15 }°

⇒ x = 6°

∴Two complementary angles are

7x = 7 x 6° = 42°

8x = 8 x 6° = 48°

Answer 2

Step-by-step explanation:

Two angles are in ratio 7:8

Let the 2 angles be 7x and 8x

Since they are supplementary angles:

7x+8x=180°

15x = 180°

X= 12°

Therefore the angles are 7×12° ,8×12°

i.e..84° and 96°
