Answer:
x = 75 degrees
Step-by-step explanation:
180 - 125 = 55
50 + 55 = 105
180 - 105 = 75
Answer:
x=5, y=8
Step-by-step explanation:
x+y=13
2x-y=2
add these two equations
3x=15
therefore x=5
apply this value in x+y=13
5+y=13
then y=13-5 = 8
Answer:
use The Explicit Formula for the Fibonacci Sequence
Step-by-step explanation:
10x^2-6x^2 = 4x^2
-64-36 = 100
4x^2 -100 = 0
(2x -10)(2x+10)
X = 2/10 and x = - 2/10
