Answer:
It's an equilateral triangle, so all angles of the triangle are 60 degree.
6x-1 = 60
x= 10.167
11x+4
x= 10.545
Step-by-step explanation:
It's an equilateral triangle, so all angles of the triangle are 60 degree.
6x-1 = 60
6x = 60+1
x= 61/6 = 10.167
To solve 11x+4:
11x+4= 180-60
11x = 120-4
11x/11 = 116/11
x= 10.545
