Answer:
Step-by-step explanation:
First of all, your formula isn't right. In general, the KE = 1/2 m * v^2
KE = 1/2 m * v^2 Multiply both sides by 2
2*Ke = m * v^2 Now divide by v^2
2*Ke/v^2 = m

What’s x = in this equation
Answer:
5m
Step-by-step explanation:
Applying Pythagoras theorem:
a² + b² = c² (where a is base length, b is the height and c is the hypotenuse of the right triangle)
3² + 4² = c²
c² = 9 + 16 = 25
c = x = [tex]\sqrt{25}[/tex] = 5
∴ x = 5m

[tex] 2\sqrt{3} [/tex]
Step-by-step explanation:
1. Expand the expression
[tex] \frac{6}{ \sqrt{3} } \times \frac{ \sqrt{3} }{ \sqrt{3} } [/tex]
2. To multiply the fractions, multiply the numerators and denominators seperately
[tex] = \frac{6 \sqrt{3} }{ \sqrt{3} \sqrt{3} } [/tex]
3. Calculate the product : when a square root of an expression is multiplied by itself, the result is that expression.
[tex] \frac{6 \sqrt{3} }{3} [/tex]
4. Reduce the fraction with 3 and the solution is :
[tex] = 2 \sqrt{ 3} [/tex]

Answer:
sum of the interior angles=900°
Answer:
900°
Step-by-step explanation:
To find any shape sum of interior angles ,
we use the formula,
