The measure of the exterior angle of the triangle is what degree?

RSB [31]

Answer:

92°

Step-by-step explanation:

By exterior angle theorem:

$(2x - 2) \degree = x \degree + 45 \degree \\ \\ (2x - 2 - x) \degree = 45 \degree \\ \\ (x - 2) \degree = 45 \degree \\ \\ (x - 2) = 45 \\ \\ x = 45 + 2 \\ \\ x = 47 \\ \\ (2x - 2) \degree = (2 \times 47 - 2)\degree \\ \\ (2x - 2) \degree = (94 - 2)\degree \\ \\ (2x - 2) \degree = 92\degree \\ \\ measure \: of \: the \: exterior \: angle \\ = 92 \degree$

it confuses me when i have to fill in the in between i just dont quite understand how to work it out please explain it clearly

prisoha [69]

Make the unknown numerator be x and unkown denominotor be y

We have : 7 - $\frac{x}{y}$ = 6 $\frac{4}{5}$

=> $\frac{x}{y}$ = 7 - 6 $\frac{4}{5}$

$\frac{x}{y}$ = $\frac{1}{5}$

So we need to fill in the box : $\frac{1}{5}$

If the answer is helpful, Brainliest please!
