Question

Two supplementry angle are in the 2:3. Find the angles​

Answer 1

$let \: two \: angles \: be \: 2x \: and \: 3x \\ \\ 2x + 3x = 180 \\ 5x = 180 \\ x = \frac{180}{5} \\ x = 36 \\ \\ 2x = 2 \times 36 = 72 \\ 3x = 3 \times 36 = 108$

Answer 2

Answer:

2x+3x=180

5x=180

x=

180

x=36

2x=2×36=72

3x=3×36=108
