Answer:

Step-by-step explanation:

if two angles are 60 degrees, the third one is also 60 degrees

that means all the sides are equal

if one side is 4x

4x+4x+4x=54

12x=54

x=4.5

Answer:

This is a triangle with 2 equal angles and equal to 60

=> this is an equilateral triangle

=> y = 60

4x.3 = 54

=> y = 60

x = 54/12 = 4.5

Solve the equation x-9 over 3 = 5 over 13

Taya2010 [7]

(x - 9)/3 = 5/13

First multiply 3 to both sides to isolate the x

(x - 9)/3(3) = 5(3)/13

x - 9 = 15/13

Next, add 9 to both sides

x - 9 (+9) = 15/13 (+9)

x = 9 15/13

Simplify.

x = 10 2/13

Answer: x = 10 2/13

hope this helps
