A=1, c=25/7(3.571429) b=?
c=hypotenuse
a=side

In this case, we are finding for a SIDE and not the HYPOTENUSE.

Using Pythagoras' theorem
side²= hyp²–side²
b²= 3.57²–1²
b²= 12.7–1
b²= 11.7
b²= √11.7
b²= 3.4(correct to 1 dp)

Therefore, b= 3.4

HOPE THIS HELPS.... IF NOT I'M SO SORRY :'(
IF IT HELPS YOU PLEASE THANK ME AND GIVE ME BRAINLIEST :)

Answer:

\frac{24}{7}=b

Step-by-step explanation:

We are given a right angled triangle.

Hypotenuse = c = \frac{25}{7}

Base = a = 1

Now we are supposed to find the perpendicular i.e. b

So, we will use Pythagoras Theorem  :

Hypotenuse^2=Perpendicular^2+Base^2

c^2=b^2+a^2

(\frac{25}{7})^2=b^2+1^2

\frac{625}{49}=b^2+1

\sqrt{\frac{625}{49}-1}=b

\frac{24}{7}=b

Hence the missing length is \frac{24}{7}.

What is √-11 in the form a+bi?
Mice21 [21]

Given:

The number is \sqrt{-11}.

To find:

The a+bi form of given number.

Solution:

We have,

\sqrt{-11}

It can be written as

\sqrt{-11}=\sqrt{-1\times 11}

\sqrt{-11}=\sqrt{-1}\times \sqrt{11}      [\because \sqrt{ab}=\sqrt{a}\sqrt{b}]

\sqrt{-11}=i\times \sqrt{11}      [\because \sqrt{-1}=i]

\sqrt{-11}=\sqrt{11}i

Here, real part is missing. So, it can be taken as 0.

\sqrt{-11}=0+\sqrt{11}i

So, a = 0 and b=\sqrt{11}.

Therefore, the a+bi form of given number is 0+\sqrt{11}i.
