Answer:
CD = 5.20 units to the nearest hundredth.
Step-by-step explanation:
Triangle BCD is a right angled triangle with m < C = 60 degrees (because triangle ABC is equilateral).
tan 60 = 9/CD
CD = 9 / tan 60
= 5.196.
The answer to your question is: CD = 5.2 units
ΔABC is equilateral, then its angles are 60°, 90° and 30°
∠C = 60°
sin 60° = 6 / hypotenuse
hypotenuse = BC = 9 / sin 60
BC = 6.9
tan 60 = 9/ CD
CD = 5.2 u
yes
x is left to right y is up and down !!
x is left to right y is up and down !! x would be (0,-1) and (0,-3)
2:3=14:21
2+2=5
35/5=7
7*2=14
7*3=21
