Simplify 4+3x=22
Step by step explanation

x = 6

Step-by-step explanation:

Rearrange terms

4  +  3  =  2 2

3  +  4   =  2 2

Subtract   4  from both sides of the equation

3x+4=22

3 + 4 − 4 = 2 2 − 4

Simplify  (Subtract the numbers )

3 = 1 8

Divide both sides of the equation by the same term

3 = 1 8

3 / 3 = 1 8 /3

Simplify  (Cancel terms that are in both the numerator and denominator

Divide the numbers )

= 6

step-by-step explanation:

< 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
