If angle y measures 65 degrees how much does x measure?

supplementary angles add up to 180°

given y=65° thus...

x+y=180°

x + 65°=180°

x=180°- 65°

x=115°

x = 115°

Step-by-step explanation:

x ; y = suplementary =>

=> x + y = 180°  } => x = 180° - 65° = 115°

    y = 65°

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap
