Step-by-step explanation:
here,,
a=3,b=10,C=120°
c^2=a^2+b^2-2ab cos120°
=(3)^2 +(10)^2 _2 (3)(10)(-1/2) [cos120°=-1/2]
=9+100-(-30)
=109+30
=139
c=(139 )1/2=11.79
c=12
Given:
The expression is:

To find:
The value of the given expression.
Solution:

It can be written as:



Therefore, the value of the given expression is 0.000008.
Answer:
5x -8y
Step-by-step explanation:
3x+2x-8y
3x and 2x are like terms so we can combine them
5x -8y
Answer: y=fx+4f
Step-by-step explanation:
There is no graph possible for this equation.
A^2-5a = 6
a^2-5a-6 = 0
Discriminant = (-5)^2-4(1)(-6) = 49
Discriminant is positive so there are two solutions
