80 = 3y+ 2y+4+1
Simplfy like terms:
80 = 5y + 5
-5 -5
75 = 5y
5 5
y = 15
The answer is A. hope this helps

The given two polygons are similar to one another ~
Sides of the given polygons are in ratio of :

to put in simple Ratio ~

So, the sides of the larger polygon are :
Now, to find the Perimeter of larger polygon ~ add the side length of all sides :


Area=1/2 times base times height
for equilateral triangle, if base is x, then height is (x√3)/2
so if base is 6 then height is (6√3)/2=3√3
area is 1/2 times 6 times3√3=3 times 3√3=9√3 sqare inches
Answer:
11
Step-by-step explanation:
those alternate angles are equal to each other
5x+4=59
5x=55
x=11
