Answer:
BC = 1.71
Step-by-step explanation:
well to start we have to know the relationship between angles, legs and the hypotenuse in a right triangle
α = 70°
a: adjacent = BC
h: hypotenuse = 5
sin α = o/h
cos α= a/h
tan α = o/a
we see that it has (angle, adjacent, hypotenuse)
we look at which meets those data between the sine, cosine and tangent
is the cosine
cos α = a/h
Now we replace the values and solve
cos 70 = a/5
0.34202 = a/5
0.34202 * 5 = a
1.7101 = a
round to the neares hundredth
a = 1.7101 = 1.71
BC = 1.71
Answer:
5x+8=118
5x=110
x=22
hope this helps
have a good day :)
Step-by-step explanation:
the answer would be the third choice which is N(0, z)
multiply all numbers together:
3*6*4*3 = 216 combinations
Okay so you should find the area and then divide it by 45
120*90= 10,800
10,800/45= 240
240 is the amount of packages you will need to cover the floor
