Answer:

Probably 5

Step-by-step explanation:

This is an extremely confusing question. Whoever wrote it most likely had a typo.

The little box in the corner of the triangle means that is 90 degrees. if that is the case, this is a simple question:

Apply pythagorean theorem (a^2 + b^2 = c^2)

In this case:

3^2 + 4^2 = x^2

x^2 = 25

x=5.

HOWEVER: the two given angles are 60 degrees and 50 degrees.

Which does not work. It creates an impossible triangle.

If m=(2x+1) and n=(6) and m+n=(9). Find x

gregori [183]

Answer:

$\Large \boxed{x=1}$

Step-by-step explanation:

Substitute m=(2x+1) and n=(6) in m+n=(9).

We are finding the value of the x variable.

$2x+1+6=9$

Add the numbers on the left side of the equation.

$2x+7=9$

Subtract 7 from both sides.

$2x+7-7=9-7$

$2x=2$

Divide both sides by 2.

$\displaystyle \frac{2x}{2}=\frac{2}{2}$

$x=1$

The value of the x variable is 1.

Kevin runs 8 miles in 84 minutes. At the same rate, how many minutes would he take to run 6 miles?

netineya [11]

Kevin runs:

8 miles -- 84 minutes;

6 miles -- x minutes.

Write a proportion:

$\dfrac{8}{6}=\dfrac{84}{x}.$

Then $8\cdox =6\cdot 84,\\ \\x=\dfrac{6\cdot 84}{8}=3\cdot 21=63\ minutes.$

Answer: it takes him 63 minutes to run 6 miles
