The measures of the angles of a triangle add to 180.
45 + 45 + 90 = 180
The measures of these three angles do add to 180, ,so there is at least one triangle with these angle measures.
Using AA triangle similarity, any triangle with the same angle measures will be similar.
From the figure you already see two triangles with angles 45-45-90. There is an infinite number of triangles with those angle measures.
Cost of each shirt bought by Brain = 14.50
Then
Cost of 2 shirts bought by Brain = 2 * 14.50
= 29
Cost of a pair of shoes = 29.99
Total amount spent by Brain before tax = 29 + 29.99
= 58.99
Percentage of sales tax that needs to be paid = 6%
Amount of sales tax that needs to be [paid = (6/100) * 58.99
= 353.94/100
= 3.54
So
the total amount spent by Brain including tax = 58.99 + 3.54
= 62.53
I hope this is the answer you were looking for.

One orange costs 0.45 so a lemon costs 55 cents more than one orange
T he x and y intercepts of the equation:
are : y-intercept is (0,-5) and x-intercept is (4,0)
So, Option D is correct.
Step-by-step explanation:
we need to identify the x and y intercepts of the equation: 
Finding x-intercept
For finding x-intercept put y=0
We are given the equation:

Solving:

So, x-intercept is (4,0)
Finding y-intercept
For finding y-intercept put x=0
We are given the equation:

Solving:

So, y-intercept is (0,-5)
the x and y intercepts of the equation:
are :y-intercept is (0,-5) and x-intercept is (4,0)
So, Option D is correct.
