Answer:
Perimeter of shape B = 50 cm
Step-by-step explanation:
Perimeter of shape A = 60 cm
Let the length of each square = x cm
Total length of free boundaries of shape A = 12x
Therefore, 12x = 60
x = 5 cm
Now length surfaces of shape B = 10x
Perimeter of shape B = 10x
= 10(5)
= 50 cm
Answer:
50 degrees
Step-by-step explanation:
in a kite the diagonals are perpendicular and the smallest one divide it in two isosceles triangles. This mean that if the see at the top one we have that the two angles of its base are both 40 degree
a triangle has the sum of interior angles that is 180 degrees
180 - 80 = 100 degrees
the height of a isosceles triangle is also its bisector
a bisector divides an angle in two congruent angles, so we have
1: 100/2 = 50 degrees
I=PRT/100
720=1000x9xT/100
72000=9000T
T=72000/9000
T=8years
