This conjecture is false, A and C don't have to be complementary angles.
Let Angle A be 100 and Angle B be 80 degrees. They are supplementary (sum of 180).
Let Angle C be 100 and Angle B is still 80 degrees. They are supplementary.
However, Angle A and Angle C are not complementary (sum of 90).
If you want me to solve for "Y" then, the answer will be,
ir if you want me to solve for "X" instead then the answer will be,
Answer: 3 + n / 6 is less than -2
Explanation:
It’s an inequality:
Quotient: division
Sum: addition
A number: the variable, n
Answer:
<u>a(n)=80*(9/10)^(n-1)</u>
Step-by-step explanation:
I think u r confused
this sequence is geometric not arithmetic
HOw we know that ??
when we get a common difference <u>that must Be equal </u>
d=72-80=-8 not equal to d=64.8-72=-7.2
So it is not arithmetic
but when we get the common ratio that also must <u>be equal </u>
r=72/80=9/10 equal to r=64.8/72=9/10
So it is geometric
By using this equation:
a(n)=a*r^(n-1)
and we have <u>a=80 , r=9/10</u>
Then <u>a(n)=80*(9/10)^(n-1)</u>

Answer:
6:5
Step-by-step explanation:
divide both numbers by using gcd/ greatest common divisor
= 12:10/ 2
=6:5
