Question

In Fig.8.8,find x and y. Is /\ ABC isosceles? If so,name it equal sides ​

Answer 1

Step-by-step explanation:

x+110=180

x=180-110

x=70°

sum of three angles of triangle is 180 degree

40+70+y=180

y=180-70-40

y=180-110

y=70°

Answer 2

Answer:

x = 70 degree

y = 70 degree

Step-by-step explanation:

X = 180 - 110                         (ANGLES ON STRAIGHT LINE SUM TO 180)

   = 70 degree

40 + x + y = 180                   (ANGLES OF A TRIANGLE SUM TO 180)

180 - 40 - 70 = y

y = 70

So, y = 70 and x = 70.
