Let c = angle TPS
This angle adds to angle 'a' to get a+c = 90. We know these angles are complementary because triangle PQR is a right triangle. The acute angles of a right triangle add to 90.
We also know that b+c = 90 for similar reasons. Triangle PST is a right triangle.
So we have these two equations
a+c = 90
b+c = 90
If we were to subtract straight down then we would end up with
a-b = 0
which solves to
a = b
after adding b to both sides

Step-by-step explanation:
Answer:
251 arrangement
Step-by-step explanation:
To know how many arrangements must be prepared in total, each amount of individual arrangement must be added, that is:
120 arrangement + 85 arrangement + 46 arrangement = 251 arrangement
Which means that for that weekend you have to prepare a total of 251 arrangements
