The angle measure of a straight line is 180°, and so if the you know that one angle off of it is (5x)°, then you know that the other section is (180 - 5x)°.
Because it's an isosceles triangle, there are two identical angles, which happen to be the angles with the measure of (5x - 30)° and (180 - 5x)°.
Since they have the same measure, 5x - 30 = 180 - 5x. Solve:
![5x-30=180-5x\\\\10x=210\\\\x=\frac{210}{10}=21](https://tex.z-dn.net/?f=5x-30%3D180-5x%5C%5C%5C%5C10x%3D210%5C%5C%5C%5Cx%3D%5Cfrac%7B210%7D%7B10%7D%3D21)
Thus,
x = 21°.
