CAN SOMEONE PLEASE HELP ME WITH THIS QUESTION

Answer:

The value of DC is 66.34.

Step-by-step explanation:

The triangles ABC and DCA are right angled triangles.

The straight line AC is a bisector for angles C and A.

The measure of ∠C is 30°.

Then the measure of angles BCA and ACD will be 15° each.

The measure of angle DAB is 150°.

Then the measure of angles DAC and BAC will be 75° each.

Now consider the right angled triangle ABC.

The measure of side AC is:

$AC^{2}=AB^{2}+BC^{2}\\AC=\sqrt{AB^{2}+BC^{2}}\\=\sqrt{4^{2}+(10\sqrt{3})^{2}}\\=\sqrt{316}$

Consider the right angled triangle DCA.

The angle DAC measure 75°.

Using the trigonometric identities compute the value of Perpendicular DC as follows:

$tan\ 75^{o}=\frac{DC}{\sqrt{316}}\\\\DC=3.732\times\sqrt{316}\\\\DC=66.34$

Thus, the value of DC is 66.34.

Help please!!!

We know that In right angle triangle c^2 = a^2 + b^2.
19^2 = 3^2 + b^2
b = (361 - 9)^1/2 = 18.761663039294
Now for angles
sin(A) = a/c = 3/19
A = sin{-1}(3/19) = 9.0847202873911
A = 9.0847202873911
sin(B) = b/c = 18.761663039294 / 19
B = sin{-1}(18.761663039294 / 19) = 80.915279712614
B = 80.915279712614

What is the solution to the equations x^2-2x+y=8 and x-y=-2

kherson [118]

Hello!!

For the first equation:

$-2x + x^2 + y = 8$ (Solve for y)

$y = -x^2 + 2x +8$

For the second equation:

x - y = -2 (Solve for y)

-y = -x - 2

-y = x + 2

Good luck :)

You are asked to create a solution that is 3 parts water and 2 parts bleach. You have 4 liters of bleach. How much water should

kifflom [539]

Step-by-step explanation:

If this is 3L water : 2L bleach then this following measures and answers are the answer.

3L:2L

?L:4L

4L/2L= 2L

so therefore

3L* 2L = 6L

6L water : 4L bleach

6L water
