The coordinates of trapezoid EFGH are E(8, 8), F(8, 10), G(1, 6), and H(4, 1). The image of EFGH under dilation is E'F'G'H'.

The coordinates of vertex F' would be (4,5). Since your original coordinates are twice the new coordinates, you'd have to divide the old coordinates by 2 to get the new coordinates of (4,5).

One fifth of the sum of two angles is 24 and half their difference is 14.Calculate the two angles

Brums [2.3K]

Let, the angles = a, b
It is given that, a+b /5 = 24
a + b = 120 --- equation (1)

a-b/2 = 14
a - b = 28 ---- equation (2)
a = 28 + b

Now, substitute this value of b in equation (1),
28 + b + b = 120
2b = 120 - 28
b = 92/2
b = 46
Now, a = 28 + b = 28 + 46 = 74

In short, Your Angles are 74 and 46

Hope this helps!
