Find the tangent ratio of angle θ. hint: use the slash symbol ( / ) to represent the fraction bar, and enter the fraction with no spaces.

Tan (Θ) = .

Step-by-step explanation:

Given  : Triangle ABC.

To find : Find the tangent ratio of angle Θ.

Solution : We have given  Triangle ABC with hypotenuse  = 17 , adjacent side =  8 unit, opposite side =  15 unit.

By the trigonometric ratio :

Tan (Θ) = .

Plug the values adjacent side =  8 unit, opposite side =  15 unit.

Tan (Θ) = .

Therefore, Tan (Θ) = .

21.4 i did it already for s1

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
