Step-by-step explanation:
X1 = 1
X2 = (X1) 2 - X1
X2 = 2 - 1
X2 = 1. implies that the second term of the sequence is 1.
This is an isosceles triangle. The angles in the legs are congruent therefore making the legs congruent as well. Hope this helps!
Answer:
11
Step-by-step explanation:
m∠1 = m∠2 {Corresponding angles}
78 - 2x = 89 - 3x
Add 3x to both sides
78 - 2x + 3x = 89
78 + x = 89
Subtract 78 from both sides
x = 89 - 78
x = 11
The right answer is 6x + 5
