Solve for x i’m having trouble finding out the answer


step-by-step explanation:


step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²


a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

These figures are similar. the perimeter and area of one are given. the perimeter of the other is al

answer:   \frac{sin40^{\circ}}{x} = \frac{sin60^{\circ}}{12}

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,


by the low of sine,

\frac{sin40^{\circ}}{x} = \frac{sin60^{\circ}}{12}

which is the required equation for finding the value of x,

\frac{x}{sin40^{\circ}}= \frac{12}{sin60^{\circ}}

x= 12\times \frac{sin40^{\circ}}{sin60^{\circ}}

x= 12\times 0.74222719896

x= 8.90672638762\approx 8.967
