Question

The measures of two supplementary angles are (3x+15)° and (2x+5)°. Find the value of x.​

Answer 1

Answer:

x=32°

Step-by-step explanation:

The sum of two supplementary angles is equal to 180°. So,

3x+15° + 2x+5° =180°

5x+20°= 180°

5x=180°-20°

x=160°/5

x=32°

Answer 2

Answer:

32°

Step-by-step explanation:

Sum of the angles = 180°

So,

3x + 15 + 2x + 5 = 180°

5x + 20 = 180°

5x = 180° - 20

5x = 160°

X = 160/5

X = 32°
