    Find the value of the unknown interior angle x in the following figures:

    Aagar

    Since, Exterior angle = Sum of interior opposite angles, therefore (i) x + 50° = 115° ⇒ x = 115° - 50° = 65° (ii) 70° + x = 100° ⇒ x = 100° - 70° = 30° (iii) x + 90° = 125° ⇒ x = 120° - 90° = 35° (iv) 60° + x = 120° ⇒ x = 120° - 60° = 60° (v) 30° + x = 80° ⇒ x = 80° - 30° = 50° (vi) x + 35° = 75° ⇒Read more

    Since, Exterior angle = Sum of interior opposite angles, therefore
    (i) x + 50° = 115° ⇒ x = 115° – 50° = 65°
    (ii) 70° + x = 100° ⇒ x = 100° – 70° = 30°
    (iii) x + 90° = 125° ⇒ x = 120° – 90° = 35°
    (iv) 60° + x = 120° ⇒ x = 120° – 60° = 60°
    (v) 30° + x = 80° ⇒ x = 80° – 30° = 50°
    (vi) x + 35° = 75° ⇒ x = 75° – 35° = 40°

  3. Asked: In:

    Verify by drawing a diagram if the median and altitude of a isosceles triangle can be same.

    Aagar

    Isosceles triangle means any two sides are same. Take ∆ABC and draw the median when AB = AC. AL is the median and altitude of the given triangle. Class 7 Maths Chapter 6 Exercise 6.1 for more answers vist to: https://www.tiwariacademy.com/ncert-solutions/class-7/maths/chapter-6/

  6. Asked: In:

    In ∆ PQR, D is the mid-point of QR. PM is _______________. PD is ________________ Is QM = MR?

    Aagar

    Given: QD = DR ∴ PM is altitude. PD is median. No, QM ≠ MR as D is the mid-point of QR. Class 7 Maths Chapter 6 Exercise 6.1 for more answers vist to: https://www.tiwariacademy.com/ncert-solutions/class-7/maths/chapter-6/
