Explanation

We use the triangle angle rule

A+B+C=180∘

50∘+40∘=90∘

180∘−90∘=90∘

Explanation

The center is the midpoint of the diameter.

Midpoint = ((-5 + 3)/2 , (6 + (-4))/2)

= (-2/2 , 2/2)

= (-1 , 1)

Explanation

$1 + tan^2 x = sec^2 x$
sec x = √(1 + (3/5)²) = √(34/25) = √34/5
cos x = 1/sec x = 5/√34
