Answer:
Area=144m²
Step-by-step explanation:
I hope you don't have any difficulty in understanding this answer
First of all, we know that 
because of its vertical angle. 
is also equal to 
because it's an interior angle.
Find two points on the graph.
example: (1,2) and (3,4)Using the equation,
,will give you the answer.
so for the example, if you plug in the numbers, you get (mobile) 1/3 
Answer:
It travels 1/5 mile in one second
Step-by-step explanation:
1/10 * 2 = 2/10 = 1/5
Since the bolt of lightning travels 1/10 mile in half a second, then to find how much it travels in one a second you simply multiply 1/10 by 2, which equals 2/10, which can be simplified to 1/5.
Hello here is a solution :
f'(x) =( sin11x)'cos11x +<span>sin11x(cos11x)'
(sin(ax+b))'=a cos(ax+b)
</span>(cos(ax+b))'=-a sin(ax+b)
f'(x) = 11 cos11xcos11x-11sin11xsin11x
f'(x) = 11(cos11x)²-11(sin11x)²
