Question

Find the value of x and y in the figures given.​

Answer 1

Answer:

A. X=45 ,Y=135

B.55=X , Y=70

C.X=70, Y=40

Step-by-step explanation:

a. abc is a isoceles triangle

as ab= ac

so angle oposite to equal sides will be also equal

abc = acb

given bac = 90

x+x+90= 180 angle sum property

2x+90=180

2x=180-90

2x=90

x= 90/2

x=45

now y

45+y=180

y=180-45

135

b. eqf =pqr =55 vertically oppoiste angle

pqr=prq =55

angles opposite to equal sides are equal

55+55+y =180

angle sum property

110+y=180

y=180-110

y=70

c.sno =70

ont = 110

180=110+70

linear pair

angle x = 70

angles opposite to equal sides are equal

70+70+y= 180

140+y=180

y=180-140

y=40
