Mathematics

Slav-nsk [51]4 years ago
6 0

Answer:

45°

Step-by-step explanation:

Using the cosine ratio in the right triangle

cosB = \frac{adjacent}{hypotenuse} = \frac{3}{3\sqrt{2} } = \frac{1}{\sqrt{2} }, hence

B = cos^{-1}( \frac{1}{\sqrt{2} } ) = 45°

The angles in degrees to radian is as follows:

-54 degrees = -3π / 10 radian

<h3>How to convert from degree to radian?</h3>

The measurement is in degrees. Let's convert it to radian with respect to π.

Therefore,

180 degrees = π radian

-54 degrees = ?

cross multiply

Hence,

angle in radian = -54 × π / 180

angle in radian = - 54π / 180

angle in radian = - 6π / 20

angle in radian = -3π / 10 radian
