All circles have the same ratio of circumference to diameter.
Answer:
are there options? if so can you add them?
Step-by-step explanation:
Answer:
The bearing of B from C is 22° counterclockwise
Step-by-step explanation:
∠CAB = 210 - 90 = 120°
Extend a line from A to the west.
drop a perpendicular line from that line to point C.
Let's call the point at the perpendicular point, M.
∠MAC = 180° - 120° = 60° because they are supplementary.
Now we have a right ∠CMA with a known hypotenuse and a known angle.
Solve for MA:
cos 60° = MA/3.8 = 1.9
Solve for MC:
sin 60° = MC/3.8 = 3.29
MB = 1.9 + 6.4 = 8.3
tan ABC = 3.29/8.3 = 21.62°
Answer:
-31/30
Step-by-step explanation:
-3/5 - 7/10 + 4/15 = -31/30
Answer:
2x-17
Step-by-step explanation:
-3(x + 5) + 5(x – 2) + 8
Lets begin:
What is -3(x+5)? I do -3×x+(-3)×5=-3x-15.
So 5(x-2) is 5×x+5×(-2)=5x-10.
Now lets sum it:
-3x-15+5x-10=2x-25
And we have 8:
2x-25+8=2x-17
