Answer:
The necklace is 4x.
Step-by-step explanation:
If the bracelet is x and the necklace is 4 times greater you would multiply the cost of the bracelet by 4. Meaning it would be X *4= 4x (x multiplied 4 times.)
This is the concept of trigonometry, to solve for the value of the other length will be given cosine rule;
c^2=a^2+b^2-2ab cos C
substituting the values in our formula we get:
c^2=12^2+18^2-2*12*18*cos 60
c^2=144+324-432 cos60
c^2=252
hence
c=sqrt252
c=15.88m
thus the fixed length will be 15.88 m
Answer:
option B
6
Step-by-step explanation:
Given in the diagram two triangles ABC and DEF,
length of the side AB = 2
length of the side DE = 12
Scale factor of triangle ABC to triangle DEF, is the scale factor of side AB to DE
AB : DE
2 : 12
1 : 12/2
1 : 6
this means triangle DEF is 6 times larger than triangle ABC
or
triangle ABC is 1/6 of triangle DEF
You should have a calculator on your phone or pc.
