Question

What is x in this problem

Answer 1

x=10

Explanation:

We know that the sum of all these angles is 180°, so, we solve for
`x` using this information:

`(9x-16)+(3x+11)+(7x-5)=180\\19x-10=180\\19x=190\\x=10`

We can now use x to find the value of each angle:

`9(10)-16=\\90-16\\=74\\\\`

`3(10)+11\\30+11\\41`

`7(10)-5\\=70-5\\=65`

Hope this helped! Have a good day.

Answer 2

`total \: angle \: for \: a \: triangle = 180 \\ then \: \\ 3x + 11 + 9x - 16 + 7x - 5 = 180 \\ 19x - 10 = 180 \\ 19x = 180 + 10 \\ 19x = 190 \\ x = (190)/(19) = 10 \\ thank \: yo`
