Answer:
The first 3 terms of the sequence 
are:
Step-by-step explanation:
Given the sequence
Here 
represents any term number in the sequence
Determining the first term
substitute n = 1 in the sequence to determine the first term
Determining the 2nd term
substitute n = 2 in the sequence to determine the 2nd term
Determining the 3rd term
substitute n = 3 in the sequence to determine the 3rd term
Therefore, the first 3 terms of the sequence are:
True
A triangle that has an angle greater than 90 degrees, it is not a right triangle
Answer:
Step-by-step explanation:
Multiply -5 by each term inside the parentheses.
Answer: 4
36.87 degrees
Step-by-step explanation:
The figure shown is a right angled triangle. It has three sides, one of which is the longest. The longest side is called the hypotenuse. Either of the shorter sides is called the opposite and the adjacent side(always the side carrying both the 90 degrees angle and the given angle).
Since the triangle is a right angled triangle,
We can apply Pythagoras theorem to get the opposite side.
Hypothenuse ^2 = opposite ^2 + adjacent ^2
5^2 = 4 ^2 + opposite ^2
opposite = √ 25 - 16
opposite = √9 = 3
Let the angle be # degrees,
Cos # = adjacent / hypothenuse
= 4/5 = 0.8
# = cos^-1 (0.8) = 36.87 degrees
