Answer:

X = 25.28

Step-by-step explanation:

By Pitagoras Theorem:

9^2 + Y^2 =24^2

81 + Y^2 = 576

Y^2 = 495

Y = 22.25

Now Y is one catet for to find X

X^2 = 12^2 + 22.5^2

X^2 = 144 + 495

X^2 = 639

X = 25.28

Answer:

x = 32

Step-by-step explanation:

The segments formed by the angle bisector will form a correct proportion when paired with their adjacent triangle sides

9/24 = 12/x

Cross multiply

9x = 24 * 12

9x = 288

x = 32

If the population of a state was 4702644 how many representatives should that state have

WARRIOR [948]

There is not an exact way to answer that question. The number of representatives each state has is determined by the population. However, the total number of house representatives has been capped at 435 since 1913. Currently, the ratio of constituents to representatives is 700,000 to 1. So if you divide the total population by 700,000 you will have an approximation of the number of representatives.

ycow [4]

Step-by-step explanation:

$sin x \: cos x \: tanx = 1 - {cos}^{2} x \\ LHS \\= sin x \: cos x \: tanx \\ =sin x \: cos x \: \times \frac{sin x}{cos x} \\ = sin x \: \times \frac{sin x}{1} \\ ={sin}^{2} x \\ = 1 - {cos}^{2} x \\ = RHS \\ \therefore \: sin x \: cos x \: tanx = 1 - {cos}^{2} x \\ Hence \: Proved.$

20% of a number is xx. What is 100% of the number? .

ludmilkaskok [199]

So you said 20% is xx???
If 20% is xx or x^2 (x squared) then 100% must be 5x^2, since 20% times 5 would get you 100%.
