Ответ:
51
Step-by-step explanation:
Hey There!
To find the perimeter of any figure all you have to do is add up all of the side lengths
5+5+7+11+7+16=53
so the perimeter is equal to 51
Note: the 18 is from the bottom length of the figure
you would have to add the 5 and 11
the extra seven is from the very right side length

part a.
angle addition postulate:
if a point lies on the interior of an angle, that angle is the sum of two smaller angles with legs that go through the given point.
from the diagram you can see that point w lies on the interior of an angle, then
m∠uvx=m∠uvw+m∠wvx.
answer: correct choice is b.
part b.
substitution property of equality:
if x = y, then x can be substituted in for y in any equation, and y can be substituted for x in any equation.
given that xy≅yz and xy=4a+4, yz=20, you can substitute instead of xy the expression 4a+4 and instead of yz the expression 20 into the iquality xy≅yz and obtain
4a+4=20
answer: correct choice is a.
