Answer:
7
Step-by-step explanation:
7.11 × 10^7
HA stands for Hypotenuse Angle theorem.
This is a special case of b. AAS theorem
This is because you would be given a side length ( hypotenuse and an acute angle). and since we would already know that a right triangle has a right angle, so we would have 2 angles and a side = AAS.
The formula that defines the sequence is f(n) = f(n-1) + 4
<h3>Recursive function</h3>
The recursive function rule is expressed as;
f(n) = f(n-1) + d
where
d is the common difference
Given the following sequence
2, 6, 10, 14, 18..
Determine the common difference
d = 6-2 = 10-6
d = 4
Substitute to have
f(n) = f(n-1) + d
f(n) = f(n-1) + 4
Hence the formula that defines the sequence is f(n) = f(n-1) + 4

#SPJ1
Yes 2x+13=21 is a linear equation
Because an octagon consists of eigth sides/edges, and 360 degrees is the total sum of the angles, we simply divide 360 by 8:
360/8 = 45.
Option A, 45 degrees
