By similar triangles:-
2 / x = x / 4
x^2 = 8
x = sqrt 8 = 2.83
y^2 = 4^2 + x^2
= 16 + 8
y = sqrt24 = 4.90
Second line on the right side of the equation it should be 2x(-13)
so then 8x - 24 + 7 = -26x
8x - 17 = -26x
then in hers she added the 8 to 26 when she should have subtracted it
it should be -17 = -34x
so 17 = 34x
1/2 = x
Answer:
60
Step-by-step explanation:
The part where y resides is an equilateral triangle. That means that all the angles are equal (along with all the sides). Remember that y is in a triangle.
So the three angles of the triangle = 180/3 = 60
That means that y = 60
Answer:y=1/3x+3
