**Answer:**

**Step-by-step explanation:**

Rotation changes nothing about the geometric relationships within the figure. Angle measures are unchanged; side lengths are unchanged.

The acute angles of an isosceles right triangle are (180° -90°)/2 = 45°. This is true regardless of the orientation of the triangle with respect to any coordinate axes.

The measures of the legs of your triangle are 0 -(-4) =** 4** = (1 - (-3)). Rotating the figure any amount in any direction around any center doesn't change that.

**Answer:**

<h3>531,441</h3>

**Step-by-step explanation:**

Let's make the length L and the width w. So, here's what we know:

L = 2w + 10

Lw = 1500

Substitute L in as 2w + 10:

w(2w + 10) = 1500.

Simplify.

2w squared +10w = 1500

Make it a quadratic equation, w = 25 or -30. Since it can't be negative, w = 25.

1500/25 = 60.

Length = 60

Width = 25
