Answer:
If 5 red shirts are added into the box, 7 : 8 is the new ratio.
Step-by-step explanation:
The number of red shirts = 16
Let the number of black shirts = k
Now as the ratio of Red Shirts : Black Shirt = 2 : 3
By RATIO OF PROPORTIONALITY:
⇒
or, 
Hence, the number of Black Shirts in the Store = 24
Now, new number pf red shirts = 16 + 5 = 21
So, by the proportionality again, ratio is

Hence, the new ratio of Red shirts : Black Shirts = 7 : 8
Given: ∠ DEF
To construct: ∠TSZ ≅ ∠DEF
Construction: Consider the attachment
Step-01: Draw a line XY and choose a point S on it as a vertex of the required angle. Further marks point T such that DE = ST
Step-02: Take an arc AB from point E in ∠DEF of any length and draw at point S which cuts at point P on XY line.
Step-03: Take another arc of length AB from point B in ∠DEF and draw from point P which cuts to the previous arc at Q.
Step-04: Now, join the point SQ and extend up to Z such that EF = SZ
Hence, ∠ TSZ will be the required congruent constructed angle to∠DEF
