We know that the three angles of a triangle always add up to 180.
Therefore, we have the equation:
55+20+x=180.
Solving for x, we get x=105.
3 is 6 less than its square.
3^2 = 9
9-3 = 6
I hope this helps!
I do not know the decimal, but I know the ratio. 7/50. I am not positive about my answer as a decimal but I think it is 7.50.
The Prove that two non-zero vectors are collinear if and only if one vector is a scalar multiple of the other is given below.
<h3>What are the proves?</h3>
1. To know collinear vectors:
∧ ⁻a ║ ⁻a
If ⁻b = ∧ ⁻a
then |⁻b| = |∧ ⁻a|
So one can say that line ⁻b and ⁻a are collinear.
2. If ⁻a and ⁻b are collinear
Assuming |b| length is 'μ' times of |⁻a |
Then | 'μ' ⁻a| = | 'μ' ⁻a|
So ⁻b = 'μ' ⁻a
