<u><em>Answers:</em></u>
AD = 10 units
BD = 12 units
<u><em>Explanation:</em></u>
<u>1- getting AD:</u>
In an isosceles triangle, the two non-parallel sides are equal.
It is given that trapezium ABCD is isosceles which means that AD = BC
<u>We are given that:</u>
BC = 10 units
<u>Therefore:</u>
AD = BC = 10 units
<u>2- getting DB:</u>
In an isosceles trapezium, the diagonals are congruent
Since the given trapezium is isosceles and AC and BD are its diagonals, therefore:
AC = BD
<u>We are given that:</u>
AC = 12 units
<u>Therefore:</u>
BD = AC = 12 units

5+1.5=6.5 yards
90-28=62 degrees
Imagine a right triangle where the
a=6.5
B=?
C=?
We use SOH-CAH-TOA
Tan(62degrees)=(x/6.5)
=12.2 yards
The reflection over the y-axis only changes the sign of the x-component so the reflected point is A' (-3, -1)
<h3>How to reflect point A over the y-axis?</h3>
Here we can't see the options, so I will teach you how to reflect any point over the y-axis.
Any point on the X-Y plane is defined by its coordinates (x, y).
If we reflect this point over the y-plane, we only change the sign of the x-component of the point.
So after the reflection, we get the point (-x, y).
Then if we apply that reflection to point A (3, -1). We will get the reflected point:
A' (-3, -1)
