Answer:
Hello,
Step-by-step explanation:
This a method knowing nothing.
1+3+5+7+9=25
425-25=400
400/5=80
Numbers are 80+1,80+,80+5,80+7,80+9 whose sum is 425.
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°
This is true, because there is an infinite amount of real numbers in both, and they are both countably infinite (so these infinities are equal). Hope this helps!
