Answer:
r = 19.2deg
Step-by-step explanation:
6r + 5 = 30 + 90 (exterior angles of a triangle)
6r = 115
r = 19.2deg (1dp)

Learn this and it can answer all ur percent problems
percent formula : is/of = %/100
36 is 75% of what number...
is = 36
% = 75
of = x.....because that is what u are looking for.
now sub into the percent formula
is/of = %/100
36/x = 75/100
cross multiply because this is a proportion
75x = 36(100)
75x = 3600
x = 3600/75
x = 48
so 36 is 75% of 48

ANSWER
EXPLANATION
The given line passes through;
(-1,-1) and it is parallel to x + y = 3.
This line given to us can be rewritten as
y=-x+1
It has slope m=-1.
The line parallel to this line also has slope m=-1.
We obtain the equation of the line using the formula:
We substitute the slope and the point to obtain:
The equation of the line is
D=rt
r=d/t
divide by t to sinlge out r
