16) It would be: 6+5+3+2 - 1+3+6+4 = 16 - 14 = 2 in.
17) -8/2 + -6/1 + -9/3+ -6/2 = -4-6-3-3 = -16
The simplest form of 19/12 is 1 and 7/12 if you want a mixed number otherwise 19/12 is as low as it will go as 19 is a prime number meaning it can only be divided by itself and 1
The triangles are similar by AAA so make ratios and solve
The single transformation that can be used to map T₁ onto T₂ is Rotate T₁ 180° about the origin.
<h3>What transformation would map T₁ onto T₂?</h3>
When a shape is rotated 180° about the origin, it means that the points go from (x, y) to (-x, -y).
The points on T₁ if rotated 180° about the origin would go from:
(-2, -2) to (2, 2)
(5, -6) to (-5, 6)
(5,0) to (-5, 0)
These are the points of T₂ so the way to map T₁ on T₂ is to use a 180° about the origin.

Try this option:
According to property such triangle
1. area=0.5*a*b, where a and b - the sides of angle 90°.
Using this equation: 180=0.5*40*b, ⇒ b=9.
2. c²=a²+b², ⇒c=√(9²+40²)=41 - the third side of the triangle;
3. Perimeter=a+b+c=9+40+41=90 cm.
answer: 90 cm.
