Answer:
7 sqrt(2)= BC
7 sqrt(2)= AB
Step-by-step explanation:
sin 45 = opp / hyp
sin 45 = BC / 14
Multiply each side by 14
14 sin 45 = BC
Sin 45 = sqrt(2)/2
14 sqrt(2)/ 2 = BC
7 sqrt(2)= BC
cos 45 = adj / hyp
cos 45 = AB / 14
Multiply each side by 14
14 cos 45 = AB
cos 45 = sqrt(2)/2
14 sqrt(2)/ 2 = AB
7 sqrt(2)= AB

Answer:
16/25
Step-by-step explanation:
length of screen B=44*(5/4)=55cm
and its width=32*(5/4)=40cm
so, screen B had dimensions 55cm by 40 cm
screen A area=44*32 cm sqr
screen B area=55*40 cm sqr
so, model A screen area/model B screen area
=(44*32)/(55*40)
=16/25
Answer:
b=-3
Step-by-step explanation:
4b+3=-9
-3 -3
subtract 3 from both sides like so. 3-3 cancels out. -9-3=-12.
4b=-12
youre left with 4b=12 so DIVIDE 4b by 4 and -12 by 4
4b/4=-12/4
4b divided by 4 is 1. -12 divided by 4 is -3
b=-3
plug -3 in for b to make sure its correct
4(-3)+3=-9
-12+3=-9
-9=-9
