Blababa [14]3 years ago
3 0

Answer:

AC=\sqrt{130}

Step-by-step explanation:

AC is the geometric mean.  Solve it using this proportion:

\frac{BC}{AC}=\frac{AC}{CD}

Now fill in the values we know:

\frac{5}{AC}=\frac{AC}{26}

Cross multiply to get

(AC)^2=130

That means that

AC = \sqrt{130}, which, in decimal form is

AC = 11.40175425

Answer:

x=35

Angle measurements of the triangle from least to greatest:

35,40,105

Step-by-step explanation:

The sum of the angles of a triangle is 180 degrees.

So we know that 40+3x+x=180.

First step is to combine the like  terms on the left hand side:

40+4x=180

Second step is to subtract 40 on both sides.

4x=140

Third step is to divide both sides by 4:

x=35

The angle that is given is the one that is 40 degrees.

So the angle whose measurement is x is really 35 degrees.

The angle whose measurement is 3x is real 3(35)=105 degrees.

In order from least to greatest we have:

35,40,105

1. What types of numbers make up the set of rational numbers?
Ad libitum [116K]

If a square root makes a perfect square, then it is rational.

Example: {√16, √100}
