An equilateral triangle is isosceles. NEVER

Equilateral has all sides which means that there will be no two sides equal and a longer/shorter side.

A right triangle is isosceles. SOMETIMES

A right triangle can have its two legs equal which has two adjacent angles measuring 45°. It can also not be isosceles.

For the first one. An equilateral triangle is one with three equal sides. An isosceles triangle is one with two equal sides. Therefore, every equilateral triangle is isosceles, but not every isosceles triangle is equilateral. So far, so book.

For the second one. Right triangles are defined as triangles that contain a right angle, where a right angle is an angle with a measure of 90°. Isosceles triangles are defined as triangles that have two sides of equal length.

Answer:

First Image: Option D

Second Image: Option D

Third Image: Option C

Fourth Image: Option B

Fifth Image: Option B

Step-by-step explanation:

First Image:

Supplementary angles is two angles whose sum is 180 degrees (straight line)
180 - 47 = 133°
? is an obtuse angle is any angle greater than 90° which checks the answer

Second Image:

A triangle angles adds up to 180°
Two angles are already given
72 + 45 + ? = 180° → 117 + ? = 180° → ? = 63°
? is an acute angle is an angle that measures between 90° and 0°

Third Image:

Supplementary angles is two angles whose sum is 180 degrees (straight line)
180 - 110 = 70°
? is an acute angle is an angle that measures between 90° and 0°

Fourth Image:

Supplementary angles is two angles whose sum is 180 degrees (straight line)
180 - 120 = 60°
we are shown a right angle which = 90°
A triangle adds up to 180°
180 - 90 - 60 = 30
? = 30°
? is an acute angle is an angle that measures between 90° and 0°

Fifth Image:

Supplementary angles is two angles whose sum is 180 degrees (straight line)
180 - 85 = 95°
? is an obtuse angle is any angle greater than 90° which checks the answer

It x, y, and z are positive intergers and 3x = 4y = 7z, then the least possible value of x + y + z is???

Dmitry [639]

$3x = 4y = 7z \\ \Rightarrow \begin{cases}3x - 4y = 0 \\4y - 7z = 0 \\ 7z - 3x = 0\end{cases} \\ \Leftrightarrow \begin{cases}x = \frac{4}{3} y\\4y - 7z = 0 \\ 7z - 3( \frac{4}{3}y) = 0\end{cases} \\ \Leftrightarrow \begin{cases}x = \frac{4}{3} y\\4y - 7z = 0 \\ 7z - 4y= 0\end{cases} \\ \Leftrightarrow \begin{cases}x = \frac{4}{3} y\\ y \\ z = \frac{4}{7}y \end{cases} \\ x,y,z\: are\: intergers\Rightarrow y=LCM(3,7)=21\Rightarrow x = 28,z = 12 \\ \Rightarrow x + y + z = 61$
