Hello!
The answer would be d = 10. Solve it like this. (v v v)
10 * 0 + 4 * d = 40 ---> 0 + 4 * 10 = 40
0 + 40 = 40
40 = 40
Hope this helps! ☺♥
Answer: All of thé above
Step-by-step explanation:
Answer:
x=30, and angle A equals 132°.
Step-by-step explanation:
Since the angles are alternate-interior, both angles A and B equal the same amount. To figure out the value of <em>x</em>, you'd need to set up your equation like this:
5x-18°=3x+42°
You would need to solve for <em>x</em>, which should equal to 30.
Once you get your <em>x</em>, you need to plug it in into the equation of angle A, which is 5x-18°:
5(30)-18°
150-18°
Angle A = 132°.
The recursive geometric sequence that models this situation is:


<h3>What is a geometric sequence?</h3>
A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.
It can be represented by a recursive sequence as follows:

With f(1) as the first term.
In this problem, the sequence is: 90.000: 81,000; 72,900; 65,610, hence:


Hence:
