For get the length of apothem write sin60 = a/4 so sqrt3 /2 = a/4 so a = 4sqrt3 /2
a = 2sqrt3
so area of base = 6(4*2sqrt3)/2 = 6*4sqrt3 = 24sqrt3 unit squared
the lateral area = 4*4*6/2 = 4*2*6 = 48 unit squared
total area = 24sqrt3 +48 = 24(sqrt3 +2) unit squared
hope this will help you
Answer:
A
Step-by-step explanation:
A triangle has 180 degrees.
So, 10 + 145 + x = 180
x = 25
This means that the angles in the triangle are:
10, 145, and 25
Using this information, only A has the same values so it is the answer
Answer:
Rs166.67
Step-by-step explanation:
Let
x -----> amount of money Arun has in his pocket at the beginning
we know that
100%-25%=75%
75%=75/100=0.75
so
The linear equation that represent this situation is
0.75x=125
Solve for x
Divide by 0.75 both sides
x=125/0.75
x=Rs166.67
Becasue there are no repeating numbers in the x coordinate
