Answer:

The required answer is c=7\sqrt{3}

Therefore the number in green box should be 7.

Step-by-step explanation:

Given:

AB = 7√2

AD = a , BD = b , DC = c , AC = d

∠B = 45°, ∠C = 30°

To Find:

c = ?

Solution:

In Right Angle Triangle ABD Sine identity we have

\sin B = \dfrac{\textrm{side opposite to angle B}}{Hypotenuse}\\

Substituting the values we get

\sin 45 = \dfrac{AD}{AB}= \dfrac{a}{7\sqrt{2}}

\dfrac{1}{\sqrt{2}}= \dfrac{a}{7\sqrt{2}}\\\\\therefore a=7

Now in Triangle ADC Tangent identity we have

\tan C = \dfrac{\textrm{side opposite to angle C}}{\textrm{side adjacent to angle C}}

Substituting the values we get

\tan 30 = \dfrac{AD}{DC}= \dfrac{a}{c}\\\\\dfrac{1}{\sqrt{3}}=\dfrac{7}{c}\\\\\therefore c=7\sqrt{3}

The required answer is c=7\sqrt{3}

What transformation transforms (a, b) to (a, −b)​?
koban [17]

We are given

(a, b) ---------------> (a, −b)​

we can see that

x-values of both points are 'a'

which is same

while y-value of first =b

y-value of second =-b

so, y becomes as -y

and we know that

when a function is reflected about x-axis

then y becomes -y

so, option-C.................Answer

I already did the work but I wanted to double change to make sure my answer are correct. The main ones I’m not sure about are 4,
Illusion [34]

Answer:

4. Composites have many non distinct prime factors, which are used more than once, such as 2,2,5,5 (the prime factors of every multiple of 100). What that means is that there can be two, three, four, or, in fact, infinitely many composite numbers that can have the same distinct prime factors.

Step-by-step explanation:

So, yes.
