Answer:

  • 63°, 27°, 117°

Step-by-step explanation:

  • Angle = x
  • Supplement = s
  • Complement = c

<u>Given</u>

  • 3s = 9c + 108°

<u>We know that:</u>

  • s = 180° - x, as per definition of supplementary angles
  • c = 90° - x, as per definition of complementary angles

<u>Substituting in the equation above and solving for x:</u>

  • 3(180-x) = 9(90 -x) + 108
  • 540 - 3x = 810 - 9x + 108
  • 9x - 3x = 918 - 540
  • 6x = 378
  • x = 378/6
  • x = 63°
  • c = 90° - 63° = 27°
  • s = 180° - 63° = 117°

Given is triangle with base = 10 cm and perpendicular height = 3 cm.

We know the formula for area of triangle is given by :-

Area = \frac{1}{2} × (Base) × (perpendicular height)

Area = \frac{1}{2} × (10) × (3)

Area = \frac{30}{2}

Area = 15 cm²

So, final answer is 15 cm².
