Answer:
20
Step-by-step explanation:
"Nine out of ten students prefer math class over lunch. How many students would not prefer math class if 200 students were asked about their preferences, if they followed the same percentage?"
Nine out of ten
Change total (ten) to 200
Ratio: 9/10 = x/200
180/200 = x/200
x = 180 prefer math
200 - 180 = 20 do not prefer math
Answer:
B = 40°
a = 23.0
b = 19.3
Step-by-step explanation:
✔️B = 180° - (90° + 50°) => sum of triangle
B = 40°
✔️Reference angle = 50°
Opp = a
Hypotenuse = 30
Adjacent = b
Find a by applying the trigonometric function, SOH:
Sin 50 = Opp/Hyp
Sin 50 = a/30
30 × Sin 50 = a
23.0 = a
a = 23.0 (nearest tenth)
To find b, apply CAH:
Cos 50 = Adj/Hyp
Cos 50 = b/30
30 × Cos 50 = b
b = 19.3 (nearest tenth)
