Step-by-step explanation: 2÷8=4 ruling out A
Unless You keep dividing by 2 over and over than the remainder will end as 2
7+2=9 13+2=15 ruling out B
16 is even, 18 is even, 20 is even, ruling out C
7*2=14 Ruling out D
Answer:
By cos Rule: c² = a² + b² -2abcosФ
c = 7.7
Step-by-step explanation:
∵ AC = 10 , BC = 16 , m∠C = 22°
∴ We can use the cos Rule:
∵ c² = a² + b² -2abcos(C)
∴ c² = (10)² + (16)² - 2 × 10 × 16 cos(22)
∴ c² = 100 + 256 - 320cos(22) = 59.301167
∴ c = 7.7
