Hello!

If you add up the squares of the two legs, it will equal the square of the hypotenuse. As we already have the hypotenuse, we will subtract.

225-81=144

Now we find the square root.

√144=12

Therefore, the other leg is 12 cm long.

I hope this helps!

Hello,

We apply the theorem of Pythagoras. Let x be the other side, y the hypotenuse and z the smallest side.

x² = y² - z²

x² = 15² - 9²

x² = 225 - 81 = 144

x = √(144) = 12 cm

Bye :)

The height of a triangle is 4 times its base. if he are of a triangle is 200cm, what is the height

uranmaximum [27]

A = (h * b) / 2
A = 200
h = 4b

200 = (b(4b) / 2
200 * 2 = b * 4b
400 = 4b^2
400 / 4 = b^2
100 = b^2
sqrt 100 = b
10 = b ..... base is 10 cm

h = 4b
h = 4(10)
h = 40 <=== height is 40 cm

The probability of A is 7/20, the probability of A intersection B is 49/400 what is the probability of B?

tino4ka555 [31]

Answer:

n(A)+n(B)-49/400=n(AUB)

n(B)=1-7/20+49/400

n(B)=(400+49-140)/400

n(B)=309/400

Determine whether the series is convergent or divergent. [infinity] n = 1 1 n√9 the series is a ---select--- p-series with p =

inna [77]

The series is a convergent p-series with p = 3

<h3>How to know it is a divergent or a convergent series</h3>

We would know that a series is a convergent p series when we have ∑ 1 np. Then you have to be able to tell if the series is a divergent p series or it is a convergent p series.

The way that you are able to tell this is if the terms of the series do not approach towards 0. Now when the value of p is greater than 1 then you would be able to tell that the series is a convergent series.

The value of $\sqrt{9}= 3$

The formular for this is

∑ $\frac{1}{n^p} \\$

where n = 1

we know it is convergent because p is greater than 1. 3>1
