from the equal angles it is an isosceles triangle, AB = AC.
4x + 1 = 2x + 23
4x - 2x = 23 - 1
2x = 22
x = 22 : 2
x = 11
----------------------
4 * 11 + 1 = 2 * 11 + 23
45 = 45
--------------
now we find BC
3x - 8
3 * 11 - 8 =
25 (is the value of BC)
Answer:

Answer:
ΔEFG is an isosceles triangle
Step-by-step explanation:
Let Amanda's age = x.
Gregory's age = x + 5.
Since Gregory is 17 years old.
17 = x + 5
x = 17 - 5
x = 12
Amanda is 12 years old.
