Answer 1

Answer:

first one says that

x and y are 80 degrees and z is 30 degrees

second one

all three angles (x ,y and z) are equal in measure which is equal to

2/3 right angle

=2/3 x 90 degrees

=60 degrees

third one

x=2/3 right angle

=2/3 x 90 degrees

=60 degrees

x=1 right angle

=90 degrees

z=1/2 right angle

=1/2  x 90 degrees

= 45 degrees
