Question

For a ramp of slope 1:1,slope in degree is?​

Answer 1

1:1 would mean one unit horizontal for every unit of vertical, or 100% slope, or 45 degree angle.

So, slope in degree will be 45°

Answer 2

The ramp makes 45 degrees angle with the ground.

Step-by-step explanation:

We are given the following in the question:

Slope of ramp = 1

Slope:

• The slope of a line is defined as the tangent of angle the line makes with x-axis.
• It is the change in y for a unit change in x.
• It is usually represented by m.

Le x be the angle that the ramp makes with the ground. Then, we can write,

$\tan x = 1\\x = \tan^{-1}(1)\\\\x = \dfrac{n\pi}{4}, n \in I\\\\x = \dfrac{\pi}{4} = 45^\circ$

Thus, ramp makes 45 degrees angle with the ground.
