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°
So listen to this logic
lets say you have 3 numbers, m,a,x where they are all positivie
m>a>x
therefor
m^2>a>2>x^2
if m and a and x are square roots, therefor we can reverse the square root
confusing sorry
square 5 and 6
5^2=25
6^2=36
the number betwe 25 and 36
that would be 32
answer is √32
goes like this
5^2<32<6^2
sqrt both sides
5<√32<6
answer is √32
D.). I think. yeah because 2 side are equal and 1 isn't.
