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
$10.63
the work is shown below
Answer:
Earns 56,500
Tax 56,500 × 10/100
=5,650
Invest = 50,850 × 50/100
= 25,425
Food = 25,425 × 30/100
=7,627.5
Shopping = 17,797.5 × 20/100
=3,559.5
Remaining = 14,237.5
X * .65 = 143
Divide both sides by .65.
x = 220
143 is 65% of 220.
