Answer:

  x = 3.75 cm

Step-by-step explanation:

If we assume ΔABC ~ ΔXYZ, then ...

  YZ/BC = YX/BA . . . . . . corresponding sides are proportional

  x/15 = 3/12 . . . . . . . . . . . fill in given values

  x = 15(3/12) = 15/4 . . . . . multiply by 15

  x = 3.75 . . . cm

If csc θ=8/7, which equation represents cotθ
TEA [102]
Sin θ = opposite leg/hypotenuse 
csc θ = hypotenuse /opposite leg =8/7

cot <span>θ = adjacent leg/opposite leg

hypotenuse =8
opposite leg =7
We need to find adjacent leg.

(Opposite leg)² +(adjacent leg)² = hypotenuse²
7² + </span>(adjacent leg)² =8²
(adjacent leg)² = 64 - 49
(adjacent leg)² = 15

adjacent leg=+/-√15
<span>WE need only positive root,
so </span>adjacent leg =√15

cot θ = √15/7 or 0.5533<span>
