Answer:
15 square units
Step-by-step explanation:
If you were to cut off the bottom triangle (separated by the dotted line), and put it on top of the other triangle, you would get a rectangle.
All you have to do is length x height
5 x 3 = 15
<h3>
Answer: B) Similar - AA</h3>
We have two pairs of angles that are congruent, so we can use the AA (angle angle) similarity theorem. Similar triangles have the same shape, so their corresponding angles are congruent.
Answer:
Below in bold
Step-by-step explanation:
I AM ASSUMING that CDEF is a Rhombus.
If it is than triangle DEG is right-angled.
so 2x + 18 + 5x + 2 = 90.
7x = 90 - 20 = 70
x = 7.
So m < CDF = 5x + 2
= 5(10) + 2
= 52 degrees.
m < DCE = 2(10) + 18 = 38 degrees.
The diagonal bisects < DCF so m < ECF = 38 degrees.
So m < DCF = 2 * 38 = 76 degrees.
Opposite angles of a rhombus are equal so m < DEF = 76 degrees.
Answer: It is rational because it can be converted to a fraction since it terminates.
