Answer:
x = 16
Step-by-step explanation:
Since ∆ABC is congruent to ∆DEC, their corresponding angles would be equal to each other.
<B is congruent to <E, therefore,
<B = <E
x + 15 = 6x - 65 (substitution)
Collect like terms
x - 6x = -15 - 65
-5x = -80
Divide both sides by -5
D ez
139, 149, 159, 169, 179, 189, 199, 209, 219, 229, 239, 249, 259.
The common difference is 13.
Let n = 52
Let d = common difference
a_52 = 139 + (52 - 1)(13)
a_52 = 139 + (51)(13)
a_52 = 139 + 663
a_52 = 802
Yes
