Question

the the ratio of angle d to angle e to angel f is 8:4:3.find the measure of angel d​

Answer 1

The sum of Angel of a triangle are 180.

So,8x+4x+3x=180

15x=180

X=12

8.12+4.12+3.12=180

And x=d, e and f

Answer 2

Answer :-

Put x in the ratio

8x + 4x + 3x = 180° [ angle sum property ]

→ 15x = 180°

→ x = 180°/15

→ x = 12°

• 8x = 8 × 12 = 96°
• 4x = 4 × 12 = 48°
• 3x = 3 × 12 = 36°
