Value of x = (1)

m(∠ABD) = (2)

 

m(\(\angle{DBE}\))

 

Value of x = (1)

m(∠DBE) = (2)

 

1. x = (1)
2. m(∠ZYQ) = (2)
3. m(∠PYQ) = (3)

1. x = (1)
2. m(∠ZYQ) = (2)
3. m(∠PYQ) = (3)

1. m(∠x) = (1) which complements a 30^o angle.
2. m(∠x) = (2) which supplements a 30^o angle.
3. m(∠x) = (3) which supplements a 105^o angle.
4. m(∠x) = (4) which complements a 75^o angle.
