Because it is a 90° angle and the legs are congruent, the legs intersect with the hypotenuse at the same angle, so the other, unnamed angle at the bottom left is equal to x.

Now we can state that:

2x + 90 = 180
2x = 90
x = 45

Hello!

<u><em>Answer: ⇒ 1/38</em></u>

Step-by-step explanation:

Convert element to fraction.

$\frac{1}{2}\div \frac{19}{1}$

Apply the fraction rule.

$\frac{1}{2}*\frac{1}{19}$

Then you can multiply by the fraction.

$\frac{1*1}{2*19}$

Multiply by the numbers.

$1*1=1$

$\frac{1}{2*19}$

$=\frac{1}{38}$

Hope this helps!

Explain how to solve (c)/(9)=3. Give the solution in you explanation

Alina [70]

Answer:

c = 27

Step-by-step explanation:

If c divided by 9 equals to 3, then the other way around would be 3 times 9 equals to c, which is how you would get 27. If you look at PEMDAS, multiplication and division are together and work the other way around when used with each other, just like addition and subtraction.

I know this is kind of a lame answer with no fancy math words to back it but please, it's the best I could do.

a. The position of a particle is given by x(t) = t3 - 3t2 - 96 +1. For what values oft is the particle at rest?

natita [175]

Answer:

t = 0 and t = 2

Step-by-step explanation:

It is at rest when the velocity = 0

The velocity is the 1st derivative

So, x'(t) = 3t^2 - 6t = 0

3t(t - 2) = 0
