430 but I don’t auctally know
The second one. You can draw it out and test it yourself.
P ( not gray)=11/32 ( not gray means black 11),
dividing (11+21=32 - altogether)
Similar to the other question, because AB is parallel to CD, you know the 72º angle corresponds to the angle on top of y.
Because that angle above y and y together make a straight line (and a straight line measures 180º), you have
72 + y = 180
Solving that for y, you get y = 108º
-5 1/5 + 7 3/4
= -5 4/20 + 7 15/20
= 2 11/20
answer 2 11/20 (2 and 11/20)
