Answer:
a. rotation; then reflection across x
Step-by-step explanation:
The transformation shown is a reflection across the y-axis.
The first part of each answer choice is a rotation 180°. That rotation is fully equivalent to reflection across both the x- and y-axes, in either order. In order to have a net effect of reflection across the y-axis, the reflection across the x-axis must be cancelled--by another reflection across the x-axis.
The reflection across y shown is equivalent to ...
rotation 180° followed by reflection across the x-axis.
The answer would be
C = 10
P = 20
Answer:
the answer to this expression is -175
Step-by-step explanation:
<span>The sum of the exterior angles of a polygon is always 360 degrees.
You have 6 sides. Each exterior angle must then be 360/60 = 60</span>°
7. Slope of AD = 4/16 = 1/4
8. ΔAEC = 3/12 = 1/4
.. ΔDFB = 2/8 = 1/4
9. The angles at E, G, and F are right angles. Lines CE and BF are parallel, so the alternate interior angles at B and C where the transversal AD crosses them are equal. The triangles of interest are similar by AA~.
10. See problem 7. The ratio is the same.
11. Hard to tell what rule they want you to state. Every axis-aligned right triangle with its hypotenuse on AD will have the same ratio of side lengths. (That's one of the features of the graph of a line. It has the same slope everywhere, measured over any distance.)
