Answer 1

• Q3. x = 20°, y = 30
• Q4. x = 30°, y = 4

Explanation:

Question 3

The triangle is equilateral

Sides are equal, internal angles are 60°

The sides

• y + 16 = 46
• y = 30

The angles

• 60° - x = 180° - (80° + 60°)
• 60° - x = 40°
• x = 60° - 40°
• x = 20°

Question 4

The bottom triangle is equilateral, the top triangle is isosceles

Sides

The equal sides of the isosceles triangle are equal with the sides of the equilateral triangle

• 5y = 20
• y = 4

Angles

• x + x = 60° as exterior angle of the isosceles triangle.
• 2x = 60°
• x = 30°
