Choose the triangle in which angle 2 is not an exterior angle.
help me...new freinds?

Answers

Answer:

The third triangle

Step-by-step explanation:

The Exterior Angle is the angle a side of a shape and a line extended from the side next to it.

So for example, the first picture shows an exterior angle because a line was extended and it forms an angle with the triangle's side.

The second picture is still an exterior angle because the angle is formed with an extended line and the triangle's side.

The third photo shows an angle formed between a random line and the triangle's side. This is not an exterior angle because the angle is not formed with any side's extension.

The fourth photo is an exterior angle because it shows the angle being formed with an extension of a line from the triangle and a side of the triangle.

Hope this helps! Feel free to ask any questions! :)

a number p divided by 7 is less than -3​

Answers

p/7 < -3
,,,,,,,,,,,,,,,

The inequality expression is p ÷ 7 < -3.

What is inequality?

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥

We have,

Number = p

Now,

A number p divided by 7 is less than -3​

This can be written as,

p ÷ 7 < -3

p/7 < 3

p < (7 x 3)

p < 21

Thus,

The number p is less than 21.
