Answer:
5/7
Step-by-step explanation:
if she had seven pages to do, and she only completes five, that means she completed 5 of the 7 of the problems. Another way to write this is 5 divide by 7 or 5/7.
assume both unknown angles as x so x+x=2x
then 180° (2x+90)=90/2
angle x =45°
another angle = 180-[90°+45°]
. 180°-135°
=45°
so angle x =45°
another angle = 45°
The second one because it has a proportional relationship
