kris kringle has alot of reindeer and snowbirds but no other pet. among his pet kris counted 42 heads and 134 legs. how many reindeer and snow birds did she have?

There are 25 reindeers and 17 snowbirds

Step-by-step explanation:

A reindeer has 4 legs while a snowbird has two legs

Let the number of reindeer be x while the number of snowbirds is y

Total heads is 42;

x + y = 42 •••••••(i)

let’s now count the legs

4(x) + 2(y) = 134

4x + 2y = 134 ••••••(ii)

divide ii by 2

2x + y = 67

y = 67 - 2x

and from i above too, y = 42-x

equate the y

67-2x = 42-x

67-42 = -x + 2x

x = 25

y = 42-x

y = 42-25

y = 17

side xy = 10

sin(x) = 4/5

cos(x) = 3/5

tan(x) = 4/3

step-by-step explanation:

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
