Answer:
36 cm
Step-by-step explanation:
Let x represent the multiplier of the ratio units. Then the perimeter is the sum of the side lengths:
77 = 25 + 4x +9x
52 = 13x . . . . . . . . subtract 25
x = 4 . . . . . . . . . divide by 13
4x = 4(4) = 16 . . . . find the other side lengths
9x = 9(4) = 36
The side lengths are 25 cm, 16 cm, 36 cm. The longest side is 36 cm.

Let's check it for fun.
So we are going to use the distributive property.
We are going to distribute all the terms in the first ( ) to all the terms in the second ( ).

Combine like terms:
Simplify the grouping of like terms:
0 times anything is 0:
y=5
x=30
Explanation: since all 3 angles of triangles are marked equal we can see that it is equilateral which means 8y=40 so y=5. Then we can find that the other triangle is an 120 30 30 triangle thus x is 30. You can also do this if you can see straight away that the big triangle is a 30-60-90 triangle and just use 90-60.
