Answer:
(-4a + b – 2c) – (3a + 2b –c)
-4a+b-2c-3a-2b+c
-7a-b-c
Step-by-step explanation:
You have not given the figure
Answer:
Let x=sinθ
2sin²θ = 5sinθ - 3
2x²=5x-3
2x²-5x+3=0
(2x-3)(x-1)=0
2x-3=0 or x-1=0
x=3/2 or x=1
sinθ=2/3 or sinθ=1
θ=arcsin(2/3) or θ=arcsin(1)
θ=0.729727656 or θ=1.57079633=π/2
Given that B lies on segment AC and AB=7.8cm , BC = 25mm
Let us convert AB to mm by multiplying with 10 that is AB = 78mm
There are totally 3 possible ways for B lying on segment AC.
Solution 1:- B lies in between A and C,
Then AC = AB+BC
=78+25 = 103 mm
Solution 2:- B lies to the right of C like ACB.
Then AB = AC+CB
78 = AC+25
AC = 78-25 = 53mm
Solution 3:- B lies to the left of A like BAC.
Then BC = BA+AC
25 = 78+AC
Since AC cannot be negative, this way is not possible.
Hence there are only 2 solutions possible.
If we are given that B lies on line joining A and C, then definitely B should lie between A and C. That means nothing but solution 1. So only one solution is possible in this case.
