Answer from: eriks1818

The center of the wall is 46 inches from the edges.

Step-by-step explanation

7 * 12 = 84

84 + 8 = 92

92 / 2 = 46

Answer from: annyork03

The answer is 3 feet 10 inches.
You need to put the nail in the middle of the wall. To find this, divide 7 feet 8 inches by 2.
First, convert 7 feet 8 inches to just inches. There are 12 inches in a foot, so multiply 7 by 12, then add 8 inches to that. Like this: 7(12)+8=92
So, the wall is 92 inches across. Now, divide 92 by 2,and the answer is 46 (inches). Now, we need to convert this back to feet and inches. We need to divide 46 by 12, then the remainder would be the number of inches and the quotient would be the number of feet. 46/12 = 3, remainder 10. So, it is 3 feet 10 inches. Hence, the nail should be placed 3 feet 10 inches from the edge of the wall.

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°,

therefore,

by the low of sine,

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

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

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

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

$x= 12\times 0.74222719896$

$x= 8.90672638762\approx 8.967$

Answer from: Quest

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
