Answer:
85m
Step-by-step explanation:
Perimeter of a rectangle = 2(l+b)
b=72m, l=?
perimeter =314m
314=2(l+72)
314/2= l+72
157=l+72
l=157-72
l=85m
Answer:
y=-2x+8
Step-by-step explanation:
Hope this helps!
In left one)
the 3 angles are equal so the sides are equal then we can say

then x is 30÷11
the right one) is exactly similar
12xy i think lol :) hope that helps a bit
