Answer:

  (a) x = 22

  (b) 46°

  (c) 44°

  (d) 180°

Step-by-step explanation:

Because the sum of the interior angles of a triangle is 180°, we know that the sum of the acute angles in a right triangle is 90°.

(a)

The sum of the marked acute angles is 90°.

  2x +(3x -20) = 90

  5x = 110 . . . . . . . . . . add 20, collect terms

  x = 22 . . . . . . . . . divide by 5

__

(b)

∠CBA = (3x -20)° = (3·22 -20)° = 46°

__

(c)

∠CAB = 2x° = 2(22)° = 44°

__

(d)

The sum of a triangle's interior angles is 180°.
