A mirror is 24 inches high and 28 inches wide. The center of the mirror will hang 514 feet from the floor on a wall that is 8 fe
Vanyuwa [196]

The distance from the top of the mirror to the ceiling once the mirror is hung on the wall is 21 inches

The dimension of the mirror is given as:

Height = 24\ in

Width = 28\ in

From the center of the mirror to the floor of the wall, the distance is:

Distance =5\frac14\ ft

So, the distance to the top of the mirror will be:

Top = 5\frac 14\ ft + \frac 12 \times Height

Substitute 24 for height

Top = 5\frac 14\ ft+ \frac 12 \times 24\ in

Top = 5\frac 14\ ft+ 12 \ in

Convert feet to inches

Top = 5\frac 14\times 12\ in+ 12 \ in

Top = 63\ in+ 12 \ in

Top = 75 \ in

The distance from the top of the mirror to the ceiling is the difference between the height of the wall and 75 inches.

So, we have:

Distance = 8\ ft - 75\ in

Convert feet to inches

Distance = 8\times 12\ in - 75\ in

Distance = 96\ in - 75\ in

Distance = 21\ in

Hence, the distance is 21 inches

The angles of a triangle are in an extended ratio of 5:7:3. What is the measure of the
uranmaximum [27]

Answer:

84°

Step-by-step explanation:

Let the measures of the triangle be 5x, 7x, 3x.

By interior angle sum postulate of a triangle.

5x + 7x + 3x = 180°

15x = 180°

x = 180°/15

x = 12°

7x = 7*12°= 84°

Measure of the largest angle = 84°
