Answer:

42

we can use trigonometric ratios (cos, sin, tan) to solve this

cos(54)=AD/20\\20cos(54)=AD\\AD=12\\

Using the pythagorean theorum we see that BD is 16

now we can use tan to solve for DC

tan(28)=16/DC\\DC=16/tan(28)\\DC=30\\30+12=42; AC=42

liubo4ka [24]

Answer:

80.

Step-by-step explanation:

Let C be the set of people who like cats and D the set of people who like dogs. Under the cardinality theorem you have

n(CUD) = n(C) + n(D) - n(CnD)[/tex], isolating the (C∩(D , you have n(C∩(D  = n(C) + n(D) - (C∪.As a total of 339 individuals, and 88 are those who do not like cats or dogs, then 251 of them are those who like cats or dogs. Then, n[tex](C∩(D  = 190 +141 -251 = 80

Is the relationship shown by the data linear? If so, model the data with an equation.
Marina CMI [18]

Answer:

4th option

Step-by-step explanation:

The relationship is linear,

putting the value of x in the right side of the equation of option 4, you'll get the value of the left side

putting, x=1

y+4=-1/2(x-1)

y=-1/2(1-1)-4

y=-4

putting, x=7

y+4=-1/2(7-1)

y=-1/2(6)-4

y=-6/2-4

y=-3-4

y=-7
