Answer:
A: SAS
B: SSS
C: AAS
D: ASA
Step-by-step explanation:
Look at the differences between terms.
The initial term is -12, and each successive term is 7 more than the preceding term:
a₂ = a₁ + 7
a₃ = a₂ + 7
Etc.
a₁₃ = a₁ + (13-1)7 = -12 + (12)7 = 72
Sin0=7/25
L = 12 inches
Using the Pythagorean theorem:
15² - 9² = L²
L² = 144
