r=- 3/8 cos (0)x t maybe is this
#1). The length of the whole circumference is (π · D) = 12π .
120° is 1/3 of 360°, so arc-AB is 1/3 of the whole circumference.
#2). 60° is 1/6 of 360°.
So arc-CD is 1/6 of the whole circumference (which is given).
#3). The circumference of the circle is (π·D) = 20π .
70° is (70°/360°) of the whole circle, so arc-XY
is (70/360) of the whole circumference.
#4). Sorry, I don't remember anything right now about
angles between chords.
I hope what I've given you so far is worth 5 points.
Answer:
x0 y0
Step-by-step explanation:
Answer: Two answers: f=-3
f=3
Step-by-step explanation:
3(f-5)=6f-12+3f
3f-15=6f-12+3f
-15+12=6f+3f-3f
F=-3
Answer2
3(f-5)=6f-12+3f
3f-15=6f-12+3f
3f-6f+3f=-12+15
F=3
