Answer:

  • x = 25°
  • x = 10°

Explanation:

Question 1

The triangle is isosceles

Use sum of the angles formula

  • 2(2x + 2) + 3x + 1 = 180
  • 4x + 4 + 3x + 1 = 180
  • 7x = 175
  • x = 175/7
  • x = 25

Question 2

The triangle is right

Sum of the acute angles

  • x + 8x = 90
  • 9x = 90
  • x = 10
