The measure of angle A in the isosceles triangle ABC is equal to 120 degrees.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
In the triangle ABC, AB = BC = 8. Triangle ABC is an isosceles triangle and ∠B = ∠C = 30° (base angles are equal).
∠A + ∠B + ∠C = 180° (sum of angles in a triangle)
∠A + 30 + 30 = 180
∠A = 120°
The measure of angle A in the isosceles triangle ABC is equal to 120 degrees.

Answer:
a^2 - 2a.
Step-by-step explanation:
Replace the y in g(y) by a - 1 and simplify.
g(a-1) = (a - 1)^2 - 1
= a^2 - 2a + 1 - 1
= a^2 - 2a.
