Question

Change -1.75 to degree measure & round to the nearest tenth.

Answer 1

d. -100.3°

EXPLANATION

The given angle in radian measure is

`- 1.75`

To convert an angle from radian measure to a degree measure, we multiply by

`(180 \degree)/(\pi)`

Therefore,

We multiply to obtain:

`- 1.75 * (180 \degree)/(\pi) = - 100.27 \degree`

We round to the nearest tenth to obtain.

`- 1.75 * (180 \degree)/(\pi) = - 100.3\degree`

Answer 2

option D

100.3°

Explanation:

We know that

π = 180°

By proportion

1 rad = 180°/π

1.75 rad = 180°(1.75)/π

= 100.26°

≈ 100.3° (nearest tenth)

Since it is in negative, -1.75 so it will be equal to -100.3° because negative sign indicate the direction on the graph, bottom.
