Answer:

1/2 pi

Step by step explanation:

Find the circumference

2πr = 2xπx2 = 4π

Find the angle of JHI

Since 1/2π is 1/8 of 4π,

Angle JHI should also be 1/8 of 360 = 45 degrees

To find area, 45/360 x π X 2^2

= 1/8 x 4π

= 1/2 π

I don’t know the answer to this question, I need help the question is in the picture!
MrMuchimi

Answer:

it is 112° .. as you will solve it like this (180-44=136) and each angle down there are equal so we will divide 136÷2 so each angle is 68° ,, finally to find x you can do it in two ways 1) (68+44) =112 or you can go with (180-68=112)

Quadrilateral A B D C is shown. In quadrilateral ABDC, AB ∥ CD. Which additional piece of information is needed to determine tha
Anna71 [15]

Step-by-step explanation:

For any quadrilateral to be a parallelogram

i) either both the pairs of opposite sides must be equal

ii) Both the pairs of opposite sides must be parallel

iii) Opposite pairs of angles must be equal

iv) Diagonals must bisect each other.

v) A pair of opposite sides must be parallel and equal

Here we are already given that AB || CD

So either we should be given that AD || BC

or we must be given that AB = CD

Here it is given AB = CD as an option.

So Option A) or the first option is the right answer that AB ≅CD is needed to prove ABCD is a parallelogram

Match each of the following complex numbers with its equivalent expression.
Yanka [14]

Answer:

Therefore

i^{110}=-1

i^{92}=1

i^{245}=i

i^{347}=-i

Step-by-step explanation:

Complex Number :

A complex number is a number that can be expressed in the form

a + bi

where a and b are real numbers, and

' i ' is called an imaginary number.

The value of i is given as

i=\sqrt{-1}

Squaring both the side we get

i^{2}=(\sqrt{-1})^{2}\\\therefore i^{2}=-1

Therefore on substituting we get

For i^110

i^{110}=(i^{2})^{55}=(-1)^{55}=-1

Similarly for i^92

i^{92}=(i^{2})^{46}=(-1)^{46}=1

Similarly for i^245

i^{245}=(i^{2})^{122}\times i=(-1)^{122}\times i=1\times i =i

Similarly for i^347

i^{347}=(i^{2})^{173}\times i=(-1)^{173}\times i=-1\times i =-i

Therefore

i^{110}=-1

i^{92}=1

i^{245}=i

i^{347}=-i
