How do you know an angle is greater than or less than a right angle?

if the angle is greater than 90°for example 120° we call it an obtuse angle while the angle 30° is less than 90° so it's an acute angle

It depends on angle number, like 4 is more than two while one is lesser than two

Step-by-step explanation:

A right angle is 90 degrees, therefore anything higher (ex:130degrees) is bigger and anything lower(45 degrees) is less, an acute angle is lesser while and obtuse is more

step-by-step explanation:

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is
