Answer:
Step-by-step explanation:
This is a 30°-60°-90° triangle, so its sides are in the ratio 1:√3:2
The side opposite the 90° angle is 11, so the side opposite the 30° angle is 11/2 = 5.5
x is opposite the 60° angle, so its length is 5.5√3 ≅ 9.5 units
here,
2x-6y= -12
2(x-3y)= -12
x-3y = -6...........eq1
x+2y=14............eq2
we can subtract the above two given equations
we get,
___________
so,
y=4
now to find the value of x we have to substitute the value of y in any of the above two equations, I choose eq2
we get,
