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.

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.

Hope this helps and please mark me as brainliest, I’m trying to level up

The solution to the system of equations 9x - 4y = 19 and 4x + 4y = 20

is x = 3 and y = 2.

What are linear and non-linear functions?

A straight line on the coordinate plane is represented by a linear function. As an illustration, the equation y = 3x - 2 depicts a linear function because it is a straight line in the coordinate plane.

Any function whose graph is not a straight line is said to be nonlinear.

Any curve other than a straight line can be a graph of it.

An example of a non-linear function is a quadratic function.

Given, Two linear equations in two variables 'x' and 'y',

9x - 4y = 19 and 4x + 4y = 20.

Now, Adding these two equations we have,

13x = 39.

x = 3 and hence y = 2.
