The greatest of the common factors of two or more numbers is
called the greatest common factor of the two or more numbers.
Oooweeeooo . . . What did I just say . . . ?
Answer:
a the difference of 17 and 9
It is an isosceles triangle which means that side BD=BC, The angles will be also equal i.e. Angle B= Angle C
<h3>Now,</h3>
- Angle B = 4x+19
- Angle C = 2x+33
![4x + 19 = 2x + 33](https://tex.z-dn.net/?f=4x%20%2B%2019%20%3D%202x%20%2B%2033)
![4x + 19 - 2x = 33](https://tex.z-dn.net/?f=4x%20%2B%2019%20-%202x%20%3D%2033)
![4x - 2x = 33 - 19](https://tex.z-dn.net/?f=4x%20-%202x%20%3D%2033%20-%2019)
![2x = 14](https://tex.z-dn.net/?f=2x%20%3D%2014)
![x = 7](https://tex.z-dn.net/?f=x%20%3D%207)
<h3>Calculating the angles:</h3>
![∠b = 4x + 19 \\ = 4 \times 7 + 19 \\ = 47](https://tex.z-dn.net/?f=%E2%88%A0b%20%3D%204x%20%2B%2019%20%5C%5C%20%20%3D%204%20%5Ctimes%207%20%2B%2019%20%5C%5C%20%20%3D%2047)
![∠c = 2x + 33 \\ = 2 \times 7 + 33 \\ = 47](https://tex.z-dn.net/?f=%E2%88%A0c%20%3D%202x%20%2B%2033%20%5C%5C%20%20%3D%202%20%5Ctimes%207%20%2B%2033%20%5C%5C%20%20%3D%2047)
Now, We will find ∠D with the help of angle sum property of triangle
![∠b + ∠c + ∠d = 180 \\ 47 + 47 + x = 180 \\ 94 + x = 180 \\ x =180 - 94 \\ x = 86](https://tex.z-dn.net/?f=%E2%88%A0b%20%2B%20%E2%88%A0c%20%2B%20%E2%88%A0d%20%3D%20180%20%5C%5C%2047%20%2B%2047%20%2B%20x%20%3D%20180%20%5C%5C%2094%20%2B%20x%20%3D%20180%20%5C%5C%20x%20%3D180%20-%2094%20%5C%5C%20x%20%3D%2086)
