x/2 - 5 =3

add 5 to each side.  this is the addition property of equality

it says when we add the same thing on both sides of the equation, we are not changing the value of the equation

we are using this to get the variable on one side and the constant on the other

x/2 -5+5 = 3+5

x/2 =8

multiply each side of the equation by 2

we are using the multiplication property of equality

it says when we multiply each side of the equation by the same thing, we are not changing the value of the equation

x/2 *2 = 8*2

x = 16

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
