Which three of the following sets of angle measures could represent the measures of the angles of a triangle?

slamgirl [31]

To figure this out we keep in mind two rules

1. A triangles sum of angles is 180

2. An angle of a triangle can not be 0

So the answer is the following

2, 3 & 4

Write 140 as the product of its prime factors.

Romashka-Z-Leto [24]

$140:\bold{2}=70\\\\70:\bold{2}=35\\\\35:\bold{5}=7\\\\7:\bold{7}=\underline{1}$

so:

$140=2\cdot2\cdot5\cdot7=\boxed{2^2\cdot5\cdot7}$

riding find the length of the hypotenuse of the right triangle use pencil and paper explain how you can interpret the Pythagorea

noname [10]

Solution

Question 1:

- Use of the area of squares to explain the Pythagoras theorem is given below

- The 3 squares given above have dimensions: a, b, and c.

- The areas of the squares are given by:

$\begin{gathered} \text{For square of length }a\to a^2 \\ \text{For square of length }b\to b^2 \\ \text{For square of length }c\to c^2 \end{gathered}$

- The Pythagoras theorem states that:

"The sum of the areas of the smaller squares add up to the area of the biggest square"

Thus, we have:

$c^2=a^2+b^2$

Question 2:

- We can apply the theorem as follows:

$\begin{gathered} 10^2+24^2=c^2 \\ 100+576=c^2 \\ 676=c^2 \\ \text{Take square root of both sides} \\ \\ c=\sqrt[]{676} \\ c=26 \end{gathered}$

Thus, the value of c is 26
