Question

Three angles which add upto 180° are in the ratio 3: 4: 8. Find them​

Answer 1

Answer:

First add all the ratios together

3 + 4 + 8 = 15

Then, divide 180 by 15

180 ÷ 15 = 12

Now,

Multiply 12 by all the numbers in the ratio

12 × 3 = 36, 12 × 4 = 48, 12 × 8 = 96

Thus we got the answer

36 : 48 : 96 = 180°

That is,

3 : 4 : 8 = 180°

Answer 2

Given question -:

Three angles which add upto 180° are in the ratio 3: 4: 8. Find them

let's try to solve the question

let the three angles be

$3x \: 4x \: and \: 8x$

Now

$3x + 4x + 8x = 180 \\ { \: according \: to \: question}$

$3x + 4x + 8x = 180$

$7x + 8x = 180$

$15x = 180$

$x = \frac{180}{15}$

$x = 12$

Thus x = 12 so,

$3x = 3 \times 12 = 36$

$4x = 4 \times 12 = 48$

$8x = 8 \times 12 = 96$

Hope this will help you
