This year the parking lot should have 16 spaces for RVs

Step-by-step explanation:

we know that

using proportion

solve for r

Multiply in cross

therefore

This year the parking lot should have 16 spaces for RVs

x ----> the number of car spaces

r ----> the number of RV spaces

we know that

----> equation A

----> equation B

substitute equation A in equation B

solve for r

\

the answer to this question is yes

< 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
