Answer:
x=13 y=10 z=3 d) 260
Step-by-step explanation:
vertex angles are congruent so you can set them equal to each other and solve
and then a straight like adds up to 180 so 180-(7(x-3)+5y)= your missing angle and then that angles is congruent to its opposite so 2(5z+15)=60
yes

25*0.08=2
25+2=27
x=3
7x-3=18
7x=18+3
7x=21
0.9[1/2-2]+0.6
.9 [1/2 -4/2] + .6
.9 [-3/2] + .6
.9 [-1.5] +.6
-1.35+.6
