Question

Find the unknown sizes of angles ​

Answer 1

Answer:

thanks for free points

Answer 2

linear pair on line BCD i.e. angle ACB+ angle ACD.

= therefore. x+ 110°= 180°

= x=180-110

= x= 70° ...

now we know that, sum of exterior angle is equal to sum of two interior angles ........

also, AB=AC hence, angle y= angle x

so, angle Y= 70°

NOW ANGLE SUM PROPERTY IN TRIANGLE ABC.

X+Y+Z= 180°

70°+70°+Z= 180°

Z= 180-140

Z= 40°

HENCE ALL ANGLES ARE FOUND........

ANGLE X= 70°

ANGLE Y= 70°

ANGLE Z= 40°

HOPEFULLY IT WILL WORK.......
