The Correct Answer is
D. 1.53, -6.53
Ответ:
X=16
Y=5
Step-by-step explanation:
For equilateral triangle, length of both sides are equal hence 18y-41=3x+1=49
Solving for x
Given that 3x+1=49
Rearranging like terms
3x=49-1=48
x=48/3=16 units
Solving for y
Considering that 18y-41=49
18y=49+41=90
y=90/18=5 units
