Answer:
Yep your right the answer is basically inequalities
Step-by-step explanation:
So yupp
The distance between the walls is: 76.56854249
Cos(60)=A/40
Cos(45)=A/80
20+56.56854249
Answer:
which triangle am confuse
Answer:
C = 14
Step-by-step explanation:
14*7= 2
Answer:
x = 14.48
Step-by-step explanation:
first we have to see that we have the measurements from all sides
and we know that the angle between side 21 and 20 is 90 degrees
well to start we have to know the relationships between angles, legs and the hypotenuse.
a: adjacent
o: opposite
h: hypotenuse
sin α = o/h
cos α= a/h
tan α = o/a
let's take the left angle as α
sin α = 21/29
α = sin^-1 (21/29)
α = sin^-1 (0.7241)
α = 46.397
Now we do the same with the smaller triangle
tan α = o/a
sin 46.397 = x/20
0.724 = x/20
0.724 * 20 = x
14.48 = x
x = 14.48
if we want to check it we can do the same procedure with the other angle
