Hello,
45° since a tangentiel angle is the half of the angle in the center corresponding.
The question is an illustration of solving equations using estimates.
The student's strategy makes sense because he uses estimation to solve the given equation
The correct sequence of equation is as follows:
We have:

Add 0 to the equation

Express 0 as 1 - 1


Add another 0

Express 0 as 3 - 3


Rewrite as:

Solve

The width of a book is 1.5 inches.
The total width of 79 books is 1.5×79
= 118.5 inches.
The cost of a 34.5 inch wide shelf is $12.95
Therefore, the cost of a 118.5 inch wide shelf will be:
(Let the cost of the 118.5 inch wide shelf be x)

x= $44.48
The ratio x : x : x√2 has two parts identical to each other ( x : x) this means two of the angles also need to be identical.
Answer: 45 -45 -90
