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:

Answer:
Step-by-step explanation:
Two Decimal places
.9(29.3) = 26.37
18(5.75)= 103.50
Three Decimal places
3.21(2.4) = 7.704
50.7(14.06)= 712.842
Four Decimal places
4.2(.938)= 3.9396
.48(12.19)= 5.8512
Answer:
3 divided by (1+2)=1
Step-by-step explanation:
bc u do parthensis first so 1+2 is 3 therfore if u divide 3 by 3 gives u one
