Answer:
a= 180-60-55=65
we know that the angle of a flat(?) ground would be 180, so we can take away the 60 and 55 to find a.
b=180-90-65=25
the sum of interior angle of a triangle would be 180, now we know what a is, also the right angle is 90, now we can take away the 90 and 65 to find b.
c=25
c is 25, because two angles on both sides of a X is the same
Answer:
Step-by-step explanation:
(6 x 10^5) + (4 x 10^4) + (5 x 10^3) + (3 x 10^2)
Answer:
37.7
Step-by-step explanation:
The formula is C = 2 • 3.14 • r , you multiply the radius by pi/3.14, then you multiply that by product by 2.
we know that
In an Arithmetic Sequence the difference between one term and the next is a constant

where
a1 is the first term
d is the common difference between terms
n is the number of months (in this problem)
case a) Mandy


------> equation 
in this equation the first month is April
case b) Bill


-------> equation 
In this equation the first month is May
With the equation
and the equation
calculate the attached table
therefore
the answer is
December
