Step-by-step explanation:
x = 0
y = | 0 + 4 | - 1
y = 4 - 1
y = 3
y = 0
0 = | x + 4 | - 1
1 = | x + 4 |
x + 4 = 1 => x₁ = 1 - 4 => x₁ = - 3
x + 4 = - 1 => x₂ = - 1 - 4 => x₂ = - 5

Answer:
Lenght of the equal sides:
Step-by-step explanation:
You can observe in the picture that the triangle have two angles that have equal measure; therefore, it is an Isosceles triangle.
By definition, Isosceles triangles have two equal angles and two equal sides.
Based on this, you can write the following equation:
Solving for "x", you get this value:
Finally, you can subsitute the value of "x" into any expression to find the lenght of the equal sides:
