Answer 2

Answer:

• x > 6
• 6 < x < 62

Step-by-step explanation:

Question 5

The sides containing the given angles 37 and 84 are of same length:

one side is marked same, the second side is common.

The sides opposite angles of 37 and 84 are proportional to those angles, therefore:

• 0< x + 14 < 2(3x - 8)

The first part:

• x > - 14

The second part:

• x + 14 < 6x - 16
• 5x > 30
• x > 6

Combination of the two is:

• x > 6

Question 6

The triangles are isosceles, because:

• The left triangle has two equal angles, so the opposite sides are congruent
• The common side with the right triangle is same as marked side, so the triangle on the right is also isosceles.

The angles between equal sides

Left triangle:

• 180° - 2*70° = 40°

Right triangle:

• 180° - 2*66° = 48°

Since 40° < 48°, the opposite sides will have same inequality due to being proportional to angles:

• 3x - 18 < 2(x + 22)
• 3x - 18 < 2x + 44
• 3x - 2x < 44 + 18
• x < 62

Same time we know the side must be a positive number:

• 3x - 18 > 0
• 3x > 18
• x > 6

So the possible values of x are:

• 6 < x < 62 or x = (6, 62)
