Answer: In degrees , The measure of 
In radians , the measure of
.
Step-by-step explanation:
We know that the formula for length of arc is given by :-
, where
= Central angle subtended by arc.
r= radius of the circle.
As per given , we have
Radius of circle : r=7 m
Length of arc : l= 8 m
Substitute these values in the above formula , we get
Hence, the measure of
.
To convert it into degrees we multiply it with 
The measure of 


Hence, the measure of 
Answer:(1,1)
Step-by-step explanation:
Its asking where both linear and curve lines are being hit,
(fxg)(0)= 1,1
Step-by-step explanation:
eqn of line : y = mx+ c
m = slope or gradient
c = y-intercept.
Lets take (1,6) = (x1,y1) and (2,3) = (x2,y2)

Substitute x = 1 and y = 6 into equation,

Therefore substituting m and c value, equation of line is

Answer:
36-54i
Step-by-step explanation:
(9+9i)(-1-5i)
v
-9-9×5i-9i-9i×5i
v
-9-45i-9i-45i^2
v
-9-45i-9i-45×(-1)
v
(-9)-45i-9i+(45)
v
36(-45i)(-9i)
v
36-54i
The equation of the circle:
( x - h )² + ( y - k )² = r²;
h = - 2, k = 5, r = 4
Answer:
A ) ( x + 2 )² + ( y - 5 )² = 16
