Answer:
Step-by-step explanation:

Answer:
slope of EF=
∠QSR=45°,
∠PTQ=90°
if RT=24
then SQ=48
square is always a rectangle
∠SUT=21°
Step-by-step explanation:
two line are perpendicular to each other if product of their slope equal to -1
=-1
slope of HE=
=-
slope of EF=
slope of EF=-1
=
slope of EF=
answer
∠QSR=45°,
∠PTQ=90°
if RT=24
then SQ=48
square is always a rectangle
given ∠SUT=3x+6
∠RUS=5x-4
∠SUT=∠RUS
3x+6=5x-4
x=5
∠SUT=3x+6=15+6=21°
∠SUT=21°
Colors of light are each bent a different amount because each color has particular wavelength
Answer:
9 cans
Step-by-step explanation
Side length of the squared ceiling = 15m
Area of a square = side x side = 15 x 15 = 
Area of paint each can covers = 25m
∴Number of paint cans needed to paint the entire ceiling =
= 9 cans
