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
Answer:
=4x2+12x+9

Step-by-step explanation:
Answer:
270 ÷ 30 = 9
Step-by-step explanation:
9x3=27
90x3 = 270
27 ÷ 3 = 9
270 ÷ 30 = 9
90 x 3 = 270
30 x 9 = 270
45. divide the first set of x and y by 2 then multiply by 9 to get 45 for y and 18 for x
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>
</span>
