Well this is an isosceles triangle so there’s corresponding angles which mean the 45 degrees on the bottom also equals the one opposite from that. So 45+45=90..... And ofc a Triangle equals 180 (so 180-90= 90) so put the choices in place of 2x and u should get c 2x45=90 (I rlly hope this makes sense it’s kinda hard to explain!)

<h3>Hello there!</h3>

Let's look at the information given to us.

- The figure is a triangle

- One angle is 45 degrees

- The other two measure x and 2x

Now, what can we do with this information?

What is the sum of all the interior angles in a triangle? According to the angle sum theorem, it's 180 degrees.

Since you're given all interior angles in the triangle, you can write it out as:

x + 2x + 45 = 180

As x, 2x, and 45 are the interior angles.

Now, how can you solve this for x?

First, move all like terms to one side. In this case, move all numbers with x in it to one side, and all those without to the other, by doing the exact operation provided to both sides.

x + 2x + 45 - 45 = 180 - 45

x + 2x = 180 - 45

And now simplify.

3x = 135

/3     /3

x = 45

Therefore, your answer is x = 45.

Y is a differentiable function of x. Choose the alternative that is the derivative dy / dx.
murzikaleks [220]

Differentiating both sides of

x^3-y^3=1

with respect to <em>x</em> yields (using the chain rule)

3x^2 - 3y^2 \dfrac{\mathrm dy}{\mathrm dx} = 0

Solve for d<em>y</em>/d<em>x</em> :

3x^2 - 3y^2 \dfrac{\mathrm dy}{\mathrm dx} = 0 \\\\ 3y^2\dfrac{\mathrm dy}{\mathrm dx} = 3x^2 \\\\ \dfrac{\mathrm dy}{\mathrm dx} = \dfrac{3x^2}{3y^2} = \dfrac{x^2}{y^2}

The answer is then D.

Find the domain of the function
aev [14]
Domain are those values of x for which function is defined. f(x) is not defined at x = 3. Therefore Domain is

let p be the number of primes less than 100, and let Q be the number of primes less than 90. What is the value of P-Q?
3241004551 [841]

The value of P - Q as described in the question above is; P -Q = 2.

According to the question;

  • P = number of primes less than 100
  • Q = number of primes less than 90

Since, we are required to determine what the value of P-Q is;

The value of P-Q is simply the number of primes between 90 and 100.

The prime numbers between 90 and 100 are; 91 and 97.

Therefore, P - Q = 2.

Can someone help me with this question? I need the statement reasoning! Thank you so much I will mark brainliest!
Sergeu [11.5K]
Triangle ABD and triangle CDB are similar because:
-it is given that angle A and angle C are equal, both 90
-angle ABD and angle CDB are equal because they are alternate interior angles
- side DB and side DB are the same length
- two triangles are equal because of AAS
