False
x-1(-3)=x+(-3)
x+3=x-3
3=-3
false
NO
The two congruent base angles tell us that this is an isosceles triangle, meaning the triangle has two congruent sides. Therefore, we can set these two expressions equal to each other and solve from there.
15x + 7 = 23x - 17
7 = 8x - 17
8x = 24
x = 3
Side = 15(3) + 7 = 45 + 7 = 52
Hope this helps!
Answer:
That looks like interior angle to me
x = 47 (since interior angles are congruent)
