the numbers are decreasing -3
Answer:
The answer is 94.2096774194
Sin x = 0.5
sin x = 1/2
sin x = opp/hyp
therefore the ratio of opp/hyp = 1/2, (opp = 1, hyp = 2)
Find the opp side
1² + x² = 2²
1 + x² = 4
x² = 4 -1
x² = 3
x =√3
The opp side is √3
cos x = opp/hyp = √3/2 = 0.87 (round to the nearest hundredths)
5a - 10*3 = 45
5a - 30 = 45
5a = 45 + 30
5a = 75
a = 15
