Answer:
10option a 10
11option d √58
12option b 16
13option d 68
14option a 16
Explanation:
To solve all these questions we will use trigonometry identity which says that
10)
TanФ = opp / adj
Tan (b) = 2/11
b = tan^-1(2/11)
b = 10.30
≈ 10
11)
hypotenuse² = height² + base²
Bc² = 3² + 7²
BC = √3²+7²
BC =√58
12)
sin(30) = opp/ hypo
sin(30) = 8 / pq
pq = 16
13)
tanB = opp / adj
B = tan^-1(17/7)
B = 67.7 ≈ 68°
14)
sin(7) = opp / hyp
sin(7) = 2/x
x = 2/sin(7)
x = 16 miles
