Question

abcd is a rhombus.find X,y,t​

Answer 1

Step-by-step explanation:

t=90° diagonals of the rhombus bisect each other at 90°

angle tcd=30° because of straight angle

angle tdc=60° because 90+30+60

angle aoy=90°

angle oay=30° alternate angle

angle y=60°

triangle aod=triangle doc

so we will prove these triangle congruent

line do is common (1)

as line db bisect ac forming equal sides.(2)

angle 90 degree common(3)

hence proved aod=doc

so x=30°by cpct
