Step-by-step explanation:
Using the ratio equality for circles
= 
(a)
Note the angle at the centre of the shaded arc is 360° - 90° = 270°, thus
= 
= 
( cross- multiply )
3C = 180 ( divide both sides by 3 )
C = 60 mm
(b)
Note the angle at the centre of the shaded arc is 360° - 135° = 225°, thus
= 
( cross- multiply )
225C = 1188 ( divide both sides by 225 )
C = 5.28 cm
27/3 = 9 cm3
the pyramid is 1/3 the volume of the cube because it fits exactly inside it
The answer is 42.
The question is asking for angle N. We know from the question that angle N is equal to angle E (Don't think about the scale factor because it only applies to the sides. They're just trying to trick you).
To find angle E:
Move numbers to the right side:
Combine like terms:
Divide both sides by 13:
The formula for angle E:
Plug in the 8:
The angle measure of E is 42. So angle N is automatically 42 too.
To solidify, we can try to use the formula which they give us for angle N:
Answer:
0.1428 if you round then it would be 0.143 2/14

Answer:
c
Step-by-step explanation:
just plug each coordinates
5=x
18=y
if its tru for both then thats the answer
