Answer:
In Right Δ ABC with right angle B,
∠A=(3 x -8)°, ∠B=90°, ∠C=(x-2)°
∠A+∠B+∠C=180°[∠ sum property of triangle]
3 x-8+90 + x-2=180
Adding and subtracting like terms
4 x-10+90=180
4 x+80=180
4 x=180-80
4 x=100
x=100/4
x=25°
∠A=3×25-8=75-8=67°
Answer: Last Option is correct.
Step-by-step explanation:
Since we have given that
Total number of tulips and daffodils = 600
Number of tulips = 150
Number of daffodils is given by
So, We can get the ratio of tulips to daffodils which is given by
So, we need to choose a random sample of flowers to represent the population.
1) He can choose 50 flowers.
As there are 1:3 of tulip and daffodils flowers but if we divide 50 by 4 it will give a decimal number, so it can't represent the required thing.
2) He can choose 25 tulips and 25 daffodils
As they are divided into 1:1 so, it can't represent the 1:3 tulip to daffodils population.
3) He can choose 15 tulips and 60 daffodils
As it is divided into 1:4 inspite of 1:3.So it can't represent the required population.
4) He can choose 10 tulips and 30 daffodils.
So, Last option which states that he can choose 10 tulips and 30 daffodils as in this case the ratio of tulips to daffodils is 1:3.
Hence, Last Option is correct.
