True or false? A theorem is a statement that can be easily proved using a corollary
lukranit [14]

The given statement "A theorem is a statement that can be easily proved using a corollary" is false.

Answer: False

<u>Step-by-step explanation:</u>

A statement that would be proven on the basis of postulates and before proven theorem is called Theorems. "Corollary", a theorem that should come from a previous theorems (part of another statement). Contrary to the definitions, this may be reversible or irreversible if they are presented in the form "if - then."

Example for theorem: The measured angles of a triangle added to 180 degree.

The theoretical aspects of geometry consists of definitions, theorems, and postulates. Basically, these are elements of geometric proof.

The longest side of a triangle similar XYZ is 39 units long. Find the other side lengths of the triangle.
Neporo4naja [7]

Answer:

The side lengths are 30, 36 and 39.

Step-by-step explanation:

To find the missing side, write a proportion using side lengths from each similar shape. A proportion is an equation that sets equal two ratios.

\frac{13}{39}=\frac{12}{y}

Find y by cross multiplying numerator and denominator of each fraction.

13y = 39(12)

13y = 468

y = 36

Find the other missing side by repeating the process.

\frac{13}{39}=\frac{10}{y}

Find y by cross multiplying numerator and denominator of each fraction.

13y = 39(10)

13y = 390

y = 30

The side lengths are 30, 36 and 39.

Write the function tan(<img src="https://tex.z-dn.net/?f=%5Cfrac%7B3%5Cpi%20%7D%7B4%7D%20-x" id="TexFormula1" title="\frac{3\pi
Alenkasestr [34]

Step-by-step explanation:

\tan( \frac{3\pi}{4}- x)  =  \frac{ \tan( \frac{3\pi}{4} ) -  \tan(x)  }{1 +  \tan( \frac{3\pi}{4} ) \tan(x)}

Since tan(3pi/4) = -1

\tan( \frac{3\pi}{4}- x)  =  \frac{ - 1 -  \tan(x)  }{1  -  \tan(x)}

=  \frac{ \tan(x)  + 1}{ \tan(x)  - 1}
