Step-by-step explanation:
LHS=(1-sin60)/cos60
=(1-√3÷2)/1÷2
=2(1-√3÷2)
=2-√3
RHS=(1-tan30)/(1+tan30)
={1-(1÷√3)}/{1+(1÷√3)}
={(√3-1)/√3}/{(√3+1)/√3}
=(√3-1)/(√3+1)
={(√3-1)(√3-1)}/{(√3+1)(√3-1)}
=(3-√3-√3+1)/(3-1)
=(4-2√3)/2
=2-√3
Therefore LHS=RHS
Answer:
Step-by-step explanation:
6 more than a number is 36: x+6=36
36 more than a number is 6: x+36=6
6 times a number is 36: 6x=36
I confused ! I don't get what your trying to say please explain better !
Answer:
(1.1 , 0.6)
Step-by-step explanation:
midpoint (x , y): ( x+x') /2 , (y+y') / 2
x = (-3.5 + 5.7) / 2 = 2.2 / 2 = 1.1
y = (-2.1 + 3.3) / 2 = 1.2 / 2 = 0.6
The answer would be 422. It's pretty easy just use a calculator
