Answer:
40.20cm approx
Step-by-step explanation:
Step one
given data
We are told that the dimension of a computer screen
diagonal= 52 cm
height= 33cm
Length = ?
Required
The length of the base of the screen
Step two
Let us use Pythagoras theorem to find the length of the base
Hyp^2= Opp^2+ Adj^2
52^2= 33^2+ L^2
2704= 1089+L^2
L^2= 2704-1089
L^2= 1615
L=√1615
L= 40.20cm approx
<u>The length is 40.20cm approx.</u>

Step-by-step explanation:
Answer:
72 adult tickets were sold and 114 child tickets were sold.
Step-by-step explanation:
x+y=186, 14x=10y=2148
x=186-y
14(186-y)+10y=2148
2604-14y+10y=2148
2604-4y=2148
-4y=-456
y=144
x=186-144 : x=72
