Answer:
n = 24
Step-by-step explanation:
(n + 18) and 2n are "complementary angles:" they add up to 90°.
Thus, n + 18 + 2n = 90. Combining the n terms results in 3n + 18 = 90.
Then 3n = 72. Dividing both sides by 3 results in n = 24.
n is 24, so n + 18 is 42 and 2n is 48. Note that 42 and 48 add up to 90.

Step-by-step explanation:
Answer:
13 is reflection over the X axis
Step-by-step explanation:
Answer:
3/3=1
Step-by-step explanation:
Angle ABC=DEF then
Side AB=DF
Side BC=EF
and Side CA=FD
So if side ac=DF
side DF=6cm.
