Cos(x) = 32/40 = 0.8 ⇒ x ≈ 37°
Here
Length = x+3
Breadth = x
We know
Perimeter of reatangle = 2(l+b)
Or 34 = 2( x+3+x)
Or 17 = 2x+3
Or 14 =2x
Or x= 7
Therefore
Length = 10 and breadth = 7 cm
Thank you

Answer:
x = -3/4
Step-by-step explanation:
Simplify the equation.
5x - 3(3x + 7) = y
5x - 3*3x + 7 *(-3) = y {Distributive rule}
5x - 9x - 21 = y
Combine like terms
-4x - 21 = y
Now, substitute the value of y = -18
-4x - 21 = -18
Add 21 to both sides
-4x = -18 + 21
-4x = 3
Divide both sides by -4
x = -3/4
Answer:
3 drops of green
Step-by-step explanation:
Green: Blue
1 : 2
We use 6 drops of blue
6/2 =3 So we need to multiply each number by 3
Green: Blue
1*3 : 2*3
3 : 6
We need 3 drops of green
