Which of the following triangles are impossible to draw? Choose all that apply.

2 answers:

8 0

These triangles are impossible:

a triangle with sides of 3 inches, 4 inches, and 8 inches
(the longest side is greater than the sum of the other 2 sides)

an obtuse equilateral triangle
(all angles in an equilateral triangle are acute)


a triangle with two right angles
The angles of ALL triangles must sum exactly to 180 degrees. Two right angles sum to 180 degrees so the third angle would have to be zero degrees.

A triangle with angles of 30, 45, and 115 cannot be drawn. The interior angles of a triangle have to add up to 180, and 30+45+115=190.
A triangle with two right angles cannot be drawn because the sum of the interior angle must be 180, and 90+90 is already 180, and we still need a third angle.
A triangle with sides of 3 in, 4 in, and 8 in cannot be drawn because the sum of two sides in a triangle must be greater than the third. 3+4=7 and 7<8

Can someone help me with this S=?

MAXImum [283]

Answer:

In order to find the value of s, we must isolate the s variable in this equation, so the first step should be subtracting 3 5/6 from both sides of this equation. In order to subtract, we multiply each denominator to get 42, and multiply the numerator by the same amount, and subtract the number from both sides:

s + 3 35/42 = 9 6/42

s = 5 13/42

Consuela and her three friends order 2 pizzas. Consuela cuts each pizza into 8 equal slices. She saves 2 slices of pizza for her

Akimi4 [234]

Let
x--------------> the number of slices eating by Consuela and her three friends

we know that
[total slices]=8*2=16 slices
[slices of pizza for her older brother]=2
x=16-2=14 slides
Consuela and her friends share the rest of the pizza, each eating the same number of slices---------> 14/4= 3.5 slides of pizza each (this part is not necessary, but it is shown in a didactic way)

the question is
What fraction of the 2 pizzas is left over?
[slices of pizza for her older brother]/[total slices]=2/16=1/8

the answer is (1/8)

A rational number is one that can be represented as the ratio of two whole numbers

$\frac{\sqrt{5}}{8}$ -----> Is not a rational number, because √5 is not a whole number, is a irrational number
