The seventh term of an AP is written as:
The eleventh term of an AP is written as:
If the 7th term is 11 times the 11th term, then;
Expand to get:
We must have a=-52 and d=5
Or
a=52 and d=-5
For the first case, the 18th term is :
For the second case,
Answer:
C.
Step-by-step explanation:
In a triangle, the longest side is opposite to the largest measure of angle. The medium side is opposite to the medium angle, while the shortest side is opposite to the smallest angle.
In ∆GHI,
✍️m<G = 95°, it is opposite to
<G is the largest angle, therefore, is the longest side.
✍️m<I = 180 - (95 + 38) = 47°.
<I is opposite to
<I is the medium angle, therefore, is the medium side.
✍️m<H = 38°, it is opposite to
<h is the smallest angle, therefore, is the shortest side.
✅This means:
