Answer:
Step-by-step explanation:
LHS = Sin² ∅ + Sin² ∅*tan² ∅
= Sin² ∅ [1 + tan² ∅ ] {Sec² ∅ - tan² ∅ = 1}
= Sin² ∅ *Sec² ∅
= Sin² ∅ * 
= Sin² ∅ /Cos² ∅
= tan² ∅ = RHS
6 times 79 = 474 so the 79th term is 474
The answer is C because the angle equal each other.
I believe you set them equal to each other.
2x+4=5x-9
x=4.3
2(4.3)+4=12.6
I think the answer is 12.6
The answer is 15.
30% of 60 = 18
45% of 60 = 27
27 + 18 = 45
60 - 45 = 15
