I'm pretty sure y=6, but I would take caution.
Solve for x by simplifying both sides of the equation, then isolating the variable.
x = 4
First look at the given numbers, especially 123 degrees which if you add up the other side it equals 180 degrees so:
180-123= 57
Ok now you know two sides of the triangle and you know that all the 3 sides add up to 360 degrees so:
57+75= 132
180-132= 48
Answer:
equation of a line= y-y¹=m(x-x¹)
y--1.8=7(x-0)
y+1.8=7x-0
y+1.8=7x
y=7x+1.8
The terms will be 3, 9, 27, 81 and so on.
notice, to get the next term, we simply multiply the current one by 3, namely the "common ratio" r = 3.
to make it plain and short, if 0 < | r | < 1, then the series sum will diverge, namely is approaching an explicit value, instead of just going on and on to infinity.
0 < | r | < 1, namely, if the common ratio is between 0 and 1, well a fraction, either negative or positive, only then the serie sum will diverge. In this case is 3 and 3 is definitely not a fraction in that range.
