Answer:

Q1

  • This is acute angle since 75° < 90°

Q2

  • This is an isosceles triangle

Q3

Exterior angle is the sum of non-adjacent interior angles:

  • 4x + 7 + 6x - 9 = 118
  • 10x - 2 = 118
  • 10x = 120
  • x = 12

m∠L = 4*12 + 7 = 48 + 7 = 55°

Q4

The triangles are congruent and corresponding sides are equal:

  • 3x - 5 = 2x + 1
  • 3x - 2x = 1 + 5
  • x = 6

Side lengths are:

  • 3*6 - 5 = 13
