Answer:
No
Step-by-step explanation:
Square root of (12^2+16^2) does not equal 19 but 20
A quarter Multiplied by a number plus five is equivalent to a number Minus seven
The length of the side between the vertices A′ and B′ is 16/7 units.
<h3>Transformation</h3>
Transformation is the movement of a point from its initial location to a new location. Types of transformation are<em> reflection, translation, rotation and dilation.</em>
Dilation is the increase or decrease in the size of a figure by a factor k. If a figure is dilated to produce an image, they are similar, hence the ratio of the corresponding sides are proportional.
The length of the side between the vertices A′ and B′ is 16/7 units.

Answer:
118°
Step-by-step explanation:
The sum of a triangle is always gonna be 180°. Adding 42° and 20° you get 62°. When you subtract 180° minus 62° you the third angle which is 118°.
In a triangle, if the sum of the squares of 2 shortest sides is less than the square of the third side, (as is the case here), the triangle is obtuse.
So, IF a and b are the 2 shortest sides then this is true.
