We know, S = n/2 [ a + l ]
Here, a = 45
l = 108
Calculation of n:
a(n) = a + (n - 1)d
108 = 45 + (n - 1)1
108 - 45 = n - 1
63 + 1 = n
n = 64
Now, substitute in the expression:
S = 64/2 [ 45 + 108 ]
S = 32 [ 153 ]
S = 4896
In short, Your Answer would be 4896
Hope this helps!

Step-by-step explanation:
angle 1= 50 degrees
x angle=50 degrees
cross multiply and you get and you get <u><em>1</em></u> as your answer
Each lap = 4.02 km
200 laps x 4.02 = 804 km total
804 km / 240 km/h = 3.35 hours = 3 hours and 21 minutes
A) 90-55=35 since a right angle is 90 total\
b)ii
Answer:
1.2 x 10⁴
Step-by-step explanation:
12,000 has 2 places of other numbers before a spam of zeroes.
Take the numbers before zeroes and put a decimal to the left of the last digit.
Last digit is 2 so a decimal goes before 2
1.2
Count how many places the decimal moved: this number is your power of 10.
12000. --> 1.2000
It moved 4 places.
12,000 = 1.2 x 10⁴
