The statue of liberty is 151 ft tall. calculate its height in meters answers
White raven [17]
1 feet = 0.3048 m

Height of statue is 151 ft.

For converting it into meter , we will multiply it 0.3048.

So 151 ft = 151 * 0.3048 meter.
                 = 46.0248 meter.

So  the height of statue in meter = 46.0248 meter.

A trellis consists of overlapping wooden slats.
mars1129 [50]

The value of x  in order for the two slats to be parallel is 6.

The measure of the indicated angle is 42°

What is an angle?

The angle is the measure of how inclined are the two surfaces, or lines with respect to each other.

For the slats to be parallel. both the given angles must be equal

So,

(3x +24)° = 7x°

Solving this expression, we get

7x -3x = 24

4x =24

x = 6°

The measure of the indicated angle is

(3x +24)° = 3x6 +24

(3x +24)° = 18+24

(3x +24)°  =42°

and 7x = 7x6 =42°

Thus, the measure of the angle is 42°
