Question

Help kinda confused

Answer 1

Triangle angles add to 180 degrees.

25+30=55 degrees, so x=180-55=125 degrees and y=180-x=55 degrees.

Answer 2

x = 125

Explanation:

y = 25 + 30 { exterior angle equals the sum of opposite interior angles }

y = 55

x + y =180 { linear pair }

x + 55 = 180

x = 180 -55

x = 125
