1) g=-y+c/x, solve for X

Sindrei [870]

Answer:

the solution $x = \frac{c}{g-y}$

Step-by-step explanation:

Step 1:-

Given problem $g=\frac{-y+c}{x}$

here l.cm is x

$g = \frac{x y+c}{x}$

cross multiplication we get ,

$g x = x y +c$

Step 2:-

subtracting x y on both sides , we get

$g x - x y = c$

taking common 'x' we get,

$x(g-y) = c$

Final answer:-

$x = \frac{c}{g-y}$

A statue is 70 cm tall. when its shadow is 61 cm? long, the shadow of a certain tree is 22 m long. how tall is the? tree

Ann [662]

Ratio and Proportions
61:70=ratio of statue

?:22=61:70
?/22=61/70
Move 22 over the equal sign
?=61*22/70
?=1342/70
?=19.1714286

The tree is 19.1714286m tall

Hope this helps!

Find θ, 0° ≤ θ < 360°, given the following information.

ludmilkaskok [199]

Answer:

210°

Step-by-step explanation:

Given

sinΘ = - $\frac{1}{2}$

Note taken the inverse sine of the positive value of the ratio, gives the related acute angle, that is

Θ = $sin^{-1}$ ( $\frac{1}{2}$ ) = 30° ← related acute angle

Thus the required angle in the third quadrant is

Θ = 180° + 30° = 210°
