Answer:
angle 1=
°
Step-by-step explanation:
to find the angle of 1 you should know angle 2, what is angle 2?
angle
° and angle
are symetrical so they have the same value.
now that we know that angle 2 is equal to
°
then what is angle 1
if the whole line has an angle of
° and angle
°.
so the equation will be :

flip the equation to find
:

the angle 1 which we found in the given equation is 135
check if my answer is correct is :

my equation is correct
56 is a decimal part of 70. 56 = 4/5 = .8
