Question

What is the value of `x` in a triangle with angles `70, 60`, and `8x + 2`?

Answer 1

`x=6`

Explanation:

Since any triangle has a sum of interior angles of `180^@`, we can set up an equation to solve for `x`:

`70+60+(8x+2)=180`
`60+(8x+2)=110`
`8x+2=50`
`8x=48`
`x=6`

`:.`, the value of `x` is `6`.
