Answer:
$170 was spent on her family
Step-by-step explanation:
$350-$180=$170 spent on her family
This is an isosceles triangle, which means that the two other angles are the same degree number.
All three angles will equal 180* after adding them together.
180*- 30*= 150*
150* / 2 = 75*
Therefore, x=75*
