Answer:
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°
I think i know the answer to that question. just wait for a sec.
the center square is 20 x 20 = 400
there are 4 12 x 20 areas
12*20 = 240*4 = 960
960+400 = 1360 square inches
Option C: 6 is the value of 
Explanation:
The given expression is 
We need to determine the value of
To find the value of , let us substitute 
in the given expression.
Thus, substituting in the expression, we have,
Adding the terms, we get,
Since, we know the absolute rule that 
and the simplified expression is of the form 
, let us apply the absolute rule in the simplified expression.
Thus, we have,
Thus, the value of is 6.
Hence, Option C is the correct answer.
