How do you express a ratio

Mathematics
1 answer:
Greeley [361]3 years ago
6 0

Answer:

Step-by-step explanation:

One way to write a ratio is as a fraction:

Example:

\frac{9}{6}

Another way is by writing it using the word "to," as "9 to 6."

The most common way or the one you will see the most is the using a colon between the two numbers, 9 : 6.

Now let me be clear that all three of these ways are actually saying the <u>EXACT SAME THING</u>!!!

STALIN [3.7K]

Answer:

ΔABC and  ΔXYZ are SIMILAR by SSS property of similarity.

Step-by-step explanation:

SSS Similarity Theorem:

Two triangles are said to be similar if their  CORRESPONDING SIDES are proportional.

In ΔABC and  ΔXYZ, if \frac{AB}{XY}  = \frac{BC}{YZ} = \frac{AC}{XZ}  , then  △ABC∼△YZX

Here, in ΔABC and  ΔXYZ

AB = 9, BC = x , AC = 12

Similarly, XY = 3, YZ = 2, ZX = 4

Here,

\frac{AB}{XY} = \frac{9}{3}  = 3\\\frac{BC}{YZ} = \frac{x}{2} \\\frac{Ac}{Xz} = \frac{12}{4}  = 3

⇒ Corresponding sides are in the ratio of 3, if BC  =6 units

Hence, if BC  = 6 units, then the ΔABC and  ΔXYZ are SIMILAR by SSS property of similarity.

Brainliest for anyone if they get this CORRECT.

(x + 8)(x - 6)

to factorise consider the factors of - 48 which sum to + 2

These are + 8 and - 6 thus

x² + 2x - 48 = (x + 8)(x - 6)

An angle in a triangle measures 138 °. The other two angles are congruent. Enter and solve an equation to find the x measure of
Juli2301 [7.4K]

Hey there! I"m happy to help!

The interior angles of a triangle add up to 180. We have 2 angles that have a value of x, so 2x+138=180.

We subtract 138 from both sides.

2x=42

We divide both sides by 2

x=21.

Have a wonderful day! :D
