For this one you have to go
2x-4+3x+14
Then combine like terms
5x+10

Divide
5/5 and 5/10
Which would be : x= 2

Then you go back to the original measure of ZCAB & ZCAE and plug it in.
So : 2(2)-4= ?
Then the other angle : 3(2)+14= ?

The answer you get for each one add them together and that will be the measure of mZDAC.
I hope this helps :)

Find the value of x. Round your answer to the nearest tenth.

natka813 [3]

That's a question about the Pythagorean Theorem.

We use the Pythagorean Theorem to find the value of one side in a right triangle.

This theorem says that:

$\boxed{a^2 = b^2 + c^2}$

a is the hypotenuse (It's the opposite side the right angle).
b and c are cathetus (They're the adjacent sides the right angle).

Okay, now, let's go to solve this problem! In our figure, we have two cathetus. Their values are 10 and 7 and we have to find the value of x (the hypotenuse). Let's change this information in that formula.

$a^2 = b^2 + c^2\\x^2 = 10^2 + 7^2\\x^2 = 100 + 49\\x^2 = 149\\x = \sqrt{149}$

Therefore, the value of x is $\sqrt{149}$ .

I hope I've helped. :D

Enjoy your studies! \o/

katrina has 2 blue ribbons for her hair. One fourth of all her ribbons are blue. How many ribbons does katrina have in all?

Alexxx [7]

Katrina has 8 ribbons in all, because 2 x 4 is 8 and that is the whole amount.

A spinner is divided into four equal sections labeled 1, 2, 3, and 4. Another spinner is divided into three equal sections label

Romashka-Z-Leto [24]

Since we are asked to compute the probability of two event with "or"
statement, then we will add the probabilities like this:
Denote A the first event and B the second event:
$P(A\cup B)=P(A)+P(B)$
A="Get an even number":
$P(A)= \frac{2}{4}= \frac{1}{2}$
B="Get section B":
$P(B)= \frac{1}{3}$
Conclusion:
$P(A\cup B)=P(A)+P(B)= \frac{1}{2} +\frac{1}{3}\\=\frac{5}{6}$
The probability is 5/6
