In triangle ABC, angle B is 90° and angle A is 45° => triangle ABC is Isosceles triangle. That means side AB = BC
Also, side AC² = AB² + BC² = 2BC²
(6√2)² = 2BC² => 36*2
BC = 6
In triangle BCD, angle D is 90° and angle B is 60° => triangle BCD is semi Equilateral triangle. That means side BD = ½BC = 6/2 = 3 which is the value of X.
Good luck
Answer:
Yes the sales manager claims can be refuted based on the calculated percentages
Step-by-step explanation:
<u>From the table attached below </u>
Total number of customers = 200
<em>Calculated percentages</em><em> </em>
customers that prefer whole life insurance = 90 = 90/200 = 45%
customers that prefer universal life insurance = 15 = 15/200 = 7.5%
customers that prefer Annuities = 95 = 95/200 = 47.5
<em>Expected percentages:</em>
whole life = 20%
Universal life = 10%
Life Annuities = 70%
There is 60% of red t-shirts 40% of them are white and blue so the reds are 60%
