PLEASE help me solve the following equations. Only part b-e will mark as brainliest
PLEASE DON'T ANSWER JUST FOR POINTS!
I hate people who do that!
I only have 50 points left cuz either people answer random words or no one answers!

Step-by-step explanation:

a) x= 5

b) x= 7

c) x= 1

d) x= 9

e) x= 11

< 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:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
