The simplification of the given algebra we see is; 9 + 3((a√a + a - a + √a)/(a - 1)) - ³/₂₀((√5 - 5)(a - 5√a)) - (a² - 4a√a - 5a)/((√a + 1)*√5 + 5))
<h3>How to Simplify Algebra?</h3>
We are given the algebra expression;
A = [3 + ((a + √a)/(√a + 1))][3 - ((a - 5√a)/(√5 + 5))]
When we multiply out, we will get;
9 + 3((a + √a)/(√a + 1)) - 3((a - 5√a)/(√5 + 5)) - [((a + √a)/(√a + 1)) * ((a - 5√a)/(√5 + 5))]
⇒ 9 + 3((a√a + a - a + √a)/(a - 1)) - ³/₂₀((√5 - 5)(a - 5√a)) - (a² - 4a√a - 5a)/((√a + 1)*√5 + 5))

Answer:
42°
Step-by-step explanation:
the exterior angle is equal to the sum of the 2 far angles from it (from the exterior angle)
so 98-56=42°

For number 1 she is incorrect because her c.o.p isn’t true for every number, and she is supposed to do division to find c.o.p.
The c.o.p is 1.25. 6/7.5=1.25
