Question

evaluate X and Y in the following Triangle ..
Y is 9 CM
But process please ​

Answer 1

Step-by-step explanation:

by ASA congruence two triangles are equal

AO=OC

2y+6=y+15

2y-y=15-6

y=9

64°=2x+4

2x=60

x=30

Answer 2

Step-by-step explanation:

AOB congruent to COD (ASA)

therefore, by cpct

AO = OC

2y+6 = y+15

》2y-y = 15-6

》y = 9

also by cpct,

angle AOD = angle COD

》64⁰ = 2x+4⁰

》2x = 64⁰-4⁰

》2x = 60⁰

》x = 30⁰

here is your answer...
