Use the side-splitter theorem to solve for x in the triangle below.

fiasKO [112]

Answer:

$x = 7$

Step-by-step explanation:

According to the side-splitter theorem, the two sides of the triangle is divided proportionally if the line that intersects both sides is parallel to the third side of the ∆.

Therefore, based on this theorem, we would have the following:

$\frac{x}{21} = \frac{8}{24}$

Solve for x

$\frac{x}{21} = \frac{1}{3}$

Multiply both sides by 21

$\frac{x}{21}*21 = \frac{1}{3}*21$

$x = \frac{21}{3}$

$x = 7$

Solve for x<br><br> 2/7x = 6<br><br> (SHOW YOUR WORK)

castortr0y [4]

Answer:

The answer to your question is x = 21

Step-by-step explanation:

Equation

$\frac{2}{7} x = 6$

- Multiply both sides by 7

$\frac{(2)(7)x}{7} = 6(7)$

- Simplify

2x = 42

- Divide both sides by 2

$\frac{2x}{2} = \frac{42}{2}$

- Simplify

x = 21

I don’t understand pls help!!

Answer:

7.9 m

Step-by-step explanation:

Use the Pythagorean theorem: a²+b²=c²

This formula can be used to solve a side of any right (90°) triangle.

c² is the length of the hypotenuse (the diagonal side of the triangle, opposite to the 90° angle)

So, c = 32m.

Sides a and b are the legs of the triangle, but we only know one side. Plug numbers into the formula:

31² + b² = 32²

961 + b² = 1024 Subtract 961 from both sides to get b² by itself.

b² = 63

√b² = √63 Square root both sides to get b by itself.

b = 7.93725

Answer is 7.9 meters, rounded to tenths place
