Quarters = x
dimes = 196 - x
10(196 - x) + 25x = 3940
1960 - 10x +25x = 3940
1960 + 15x = 3940
15x = 1980
x = 132
169 - 132 = 64
Therefor there are 132 quarters and 64 dimes
Answer:
Theta = 52.1
Step-by-step explanation:
sin theta = opp / hyp
sin theta = 15/19
Take the inverse sin of each side
sin^-1 sin theta = sin^1- (15/19)
theta =52.13635364
To the nearest tenth
Theta = 52.1
