Factorise the following fully: 12x³-4²

its adding 5.5 each time

step-by-step explanation:

answer: it is 8

step-by-step explanation:

you know why its 8

we know that

1) the inscribed angle measures half of the arc it comprises.

so

m∠dgf= > expression

2) the opposite angles in an inscribed quadrilateral are supplementary angles

so

m∠dgf=

m∠dgf=°

substitute in the expression to find the value of arc ef

therefore

the answer is

the measure of the arc ef is

1.m=2

2.m=-6

3.m=3

4.m=1/2
