Question

ABC is an equilateral triangle, solve for both x and y

Answer 1

Answer: x=16 and y=5

Step-by-step explanation:

Set each side equal to 49, so 3x+1=49 and 18y-41=49. For the first equation, subtract 1 on both sides to get 3x=48, then divide both sides by 3 to get 16. For the second equation, add 41 to both sides to get 18y=90. Divide both sides by 90 to get 5.

Answer 2

Since it is an equilateral triangle, all sides would be equal I.e. AB=BC=AC


So,
3x+1=49
Or, 3x=49-1
Or, x=48/3
.•. x=16,,

Also,
18y-41=49
Or, 18y=49+41
Or, y=90/18
.•.y=5,,
