Answer:
(-2,-1)
Step-by-step explanation:
Using the graph find the coordinates for A and B.
A (-4,2) and B is (0,-4)
Midpoint formula is (x1 + x2)/2 , (y1+y2)/2
x value of the midpoint= (-4+0)/2 = -2
y value of the midpoint= (2 + -4)/2 = -2/2= -1
Midpoint is (-2, -1)
Answer:
The answer would be D, or 
Step-by-step explanation:
A is 540
B is 30
C is 720
D is 360
Answer:
n = 6
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin30° = 
, then
sin30° = 
= 
= ( cross- multiply )
2n = 12 ( divide both sides by 2 )
n = 6
Answer:
214°
Step-by-step explanation:
The arc subtending an angle at the centre are equal, that is
arc ED = 90° and
arc DF = 360° - (90 + 146)° = 360° - 236° = 124°
Thus
arc EDF = arc ED + arc DF = 90° + 124° = 214°
Answer:
4.71 in. difference
Step-by-step explanation:
so, the radius of the smaller saw is 1.25 and the diameter is double the radius. so it is 2.5 in diameter. the larger saw is 1.5 in greater which is 4 in.
to find circumference, you have to use the solution C = πd or circumference = pi x diameter.
3.14 x 2.5 = 7.85
4 x 3.14 = 12.56
subtract 7.85 from 12.56 to get your answer! i hope this helps!
