10°

Step-by-step explanation:

180-20 = 160

<BCA = 160°

AC=CB because its Radius

so the angle for <CBA and <BAD also the same

(180 - 160) ÷ 2 = <BAD

<BAD = 10°

Answer:

75.062c $m^{2}$

Step-by-step explanation:

To find the missing side use pythagorean theorem

So $6^{2} +b^2=8.5^2$

Solve for b, b= 6.021

To find the area use $\frac{1}{2}$ bh

So $\frac{1}{2}$ (6.021+19)(6)= area

And you get 75.062
