Answer: First option is correct.
Step-by-step explanation:
Since we have given that
4.05, 1.35, 0.45, 0.15, ...
Since it is a geometric sequence.
So, here, a = 4.05
r =
So, we know the formula for nth term in geometric sequence.
Hence, First option is correct.
Step-by-step explanation:
Sorry its messy but if you cant understand tell me
The measure of the angle m∠Q is 30.8 degree after applying the law of cosine.
<h3>What is the triangle?</h3>The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.
Let's suppose the angle m∠Q is A
So applying law of cosine:
CosA = 0.859
A = 30.75 ≈ 30.8 degree
Thus, the measure of the angle m∠Q is 30.8 degree after applying the law of cosine.
