Answer:
n=28,m=6
Step-by-step explanation:
Rearrange to give 4704 = m * n^2
Express 4704 in its prime factorisation:
2^5 * 3^1 * 7^2
We know that n must be as large as possible and, because it is squared, be the even numbers.
We get n^2 = 2^4 * 7^2 so n = 2^2*7 = 28
m is the leftovers
2^1*3 = 6
The value of ∠ABC is 64 degree at x = 19 degree ,therefore Yin is not right about the value of x .
<h3>What is a Triangle ?</h3>
A triangle is a polygon with three sides , angles and vertices.
It is given that
m∠ABC = (4x – 12)°
m∠ACB = (2x + 26)°
Let m∠ACB = y degree
It is asked that if x =19 degree , is the triangle equilateral
m∠ABC = (4x – 12)° = 4 *19 -12 = 64 degree
As in an equilateral triangle , the angles are all equal and equal to 60 degree.
If the value of ∠ABC is 64 degree at x = 19 degree ,therefore Yin is not right about the value of x .

Sin75° = Sin(30° + 45°)
= Sin30°.Cos45° + Sin45°.Cos30°
= 1/2 . √2/2 + √2/2.√3/2
= √2/2 ( 1/2 + √3/2 )
= √2/2 ((1+√3 ) /2 )
= (√2 + √6 )/ 4
