Answer/Step-by-step explanation:
Reference angle = θ
Opposite side = 11.9
Adjacent side = 10
Applying the trigonometric ratio, TOA, we have:
Tan θ = opp/adj
Tan θ = 11.9/10
θ = tan^{-1}(11.9/10)
θ = 49.9584509° ≈ 50.0° (to one d.p)
Apply pythagorean theorem to find AB:
Thus:
AB = √(11.9² + 10²)
AB = √241.61
AB ≈ 15.5 (to 1 d.p)
Answer:
2:1
Step-by-step explanation:
There are 600 azuki beans and 300 Lima beans. 600/300 simplified is 2:1 :DD
Answer:
v = 10
Step-by-step explanation:
6v + 6 + 2v + 4= 90°
8v + 10 = 90
8v = 90 - 10
8v = 80
v = 80/8
v = 10.
Answer:
42
Step-by-step explanation:
Forming an algebraic equation and solving:
Let the number she thought = 'x'
5/6 of the number :
Multiply both sides by 6
5x = 35 * 6
Divide both sides by 5,
The first choice (1) is the answer.
