Question

answer this..
find x and y in the given triangle ABC

Answer 1

Answer:

x=90 degrees

y=60 degrees

Step-by-step explanation:

120+y=180 degrees  (linear pair)

y=180-120=60 degrees

x+y+30=180 degrees.     (angle sum property)

x=180-90=90 degrees

Answer 2

Answer:

x = 90°, ye = 60°

Step-by-step explanation:

y = 180 - 120

y =60

30 + x + y = 180

30 + x + 60 = 180

x + 90 = 180

x = 180 - 90

x = 90
