Answer:
n = 1.125
Step-by-step explanation:

(Use Cross Product)
40n = 15 × 3
40n = 45
n = 1.125
Answer: uhh
Step-by-step explanation:
I really don’t know how to do it.
Answer:
(9, 27 )
Step-by-step explanation:
Since the dilatation is centred at the origin, multiply each of the coordinates of the original point by the scale factor of 3
(3, 9 ) → (3(3), 3(9)) → (9, 27 )
I think it is asking for the answer, therefore it would be AB = 10.7
A) The hypotenuse is the longest side of the triangle .In the figure EG is the hypotenuse.The given angle is <G=40 degrees.The side adjacent is FG= 10 units.
The question is asking us to find the trigonometry ratio which will help us find EG.We can use cos as cos is ratio of adjacent and hypotenuse.

B) Cos 40 =0.766.
Substituting tan40 value we have:

EG=13.05.
C)Sum of angles in triangle is 180.
<E+<F+<G=180
<E+90+40=180
<E+130=180
<E=50 degrees.
D) 
EF=8.39
E) Area of triangle EFG= 
A rea of the triangle = 
Area= 54.75 square units.
