Reflect (1, -4) over the x-axis. Then translate the result up 3 units.
What are the coordinates of the final point?

(4,4)

Step-by-step explanation:

(1,-4) reflected over the x-axis is (1,4). Then translated 3 units up is (4,4). Hope this helps

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}
