Question

I need help with finding out the value of x in these angles!! Can someone help me on this one?

Answer 1

3x°+25°+2x°=180°

5x°=180°-25°

5x°=155°

x=31

3x°+25°=93°+25°=118°

2x°=62°

118° and 62°

x=31

Answer 2

Supplementary

Explanation:

The 2 angles form a straight angle and are therefore supplementary, hence

3x + 25 + 2x = 180

5x + 25 = 180 ( subtract 25 from both sides )

5x = 155 ( divide both sides by 5 )

x = 31

Hence

3x + 25 = (3 × 31 ) + 25 = 93 + 25 = 118°

2x = 2 × 31 = 62°

The 2 angles are 118° and 62°
