chubhunter [2.5K]

ANSWER

$\sin(40) \degree = 0.6428$

EXPLANATION

The sine and cosine ratios are complementary.

This means that:

$\cos(x \degree) = \sin(90 - x) \degree$

We were given that,

cos(50°)=0.6428

We want to find the sine of the complement of this angle.

$\cos(50\degree) = \sin(90 -5 0) \degree$

$\cos(50\degree) = \sin(40) \degree$

This implies that,

$\sin(40) \degree = 0.6428$

Answer:

$\huge\boxed{\sf x = 20}$

Step-by-step explanation:

=> Since it is an equilateral (Having all angles and all sides equal) triangle, so every angles will be equal to the other.

=> The sum of the measures of interior angles of triangle add up to 180 degrees.

So,

3x + 3x + 3x = 180

9x = 180

Divide both sides by 9

x = 20
