You need the Law of Cosines here, since you only have 1 angle measure. If you had 2 you could use the Law of Sines, but nevertheless, we'll get there. The Law of Cosines for our particular set of info looks like this:
. Simplifying a bit we get
and
. Taking the square root of that and considering the principle root only, x = 39.2, second choice down.
I believe it would be your first option
(18, 27) 3/4
6x2 is not 66, you would need to multiply by 11 instead of 2 because 6x11 is 66 thus getting the correct answer!!!! Hope this helps.
Answer:
180 degrees rotation
Step-by-step explanation:
Solution:
- The congruency statements are as follows:
Angles: L ≅ X
M ≅ Y
N ≅ Z
Sides: LM ≅ XY
MN ≅ YZ
LN ≅ XZ
Transformation:
L ( -4 , 1 ) ------- > X ( 4 , - 1 )
( x , y ) -----------> ( -x , -y )
180 degrees rotation
