Step-by-step explanation:

What is a triangle?

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted.

Basic rule:

A triangle must be tri-sided, means it must have three sides which is only possible if the sum of the smaller two sides is greater than the third side. Otherwise, a triangle is not physically possible.

A- 2+3 = 5 hence not a triangle.

B- 3+7 > 9 hence a triangle.

C- 4+5 < 9.5 hence not a triangle.

D- 5+6 < 12 hence not a triangle.

Diagonals make 45 degree angles with the sides of a square. true or false?

Dima020 [189]

True, because the sides of a square are usually 90 degrees, and when you add a diagonal it should split that in half.

In a certain triangle x,y,z represents side lengths if x=7 and z=5 what must be true about y

irga5000 [103]

Answer:

$2 < y < 12$

Step-by-step explanation:

Given

$x = 7$

$z = 5$

Required

What must be true about y?

To answer this, we first calculate the range as follows;

$Minimum = |x - z|$

and

$Maximum = |x + z|$

For Minimum, we have:

$Minimum = |7 - 5|$

$Minimum = |2|$

$Minimum = 2$

For Maximum, we have:

$Maximum = |7 + 5|$

$Maximum = |12|$

$Maximum = 12$

The values of y are then bounded by the following:

$Minimum < y < Maximum$

This gives

$2 < y < 12$

Amanda spent $73 on shirts. Tee Shirts cost $9 and long sleeve shirts cost $11. IN she bought a total of 7, then how many of eac

pentagon [3]

Answer:

2 tee shirts

5 sleeves

Step-by-step explanation:

Let the number of shortsleeves be S and longsleeves L.

Total is 7

That is

L + S = 7

Total money spent is $73, while shorts cost 9 and longs 11

Hence,

9S + 11L = 73

We now have two equations we can solve simultaneously. From the first equation,

L = 7 - S

Putting this in equation 2

9s + 11(7 - S) = 73

9s + 77 - 11S = 73

2S = 4

S = 2

Since s = 2, then L = 5
