Answer 1

Answer:

2. sum of interior angles in triangle ️ = 180 degrees

as it was right angled triangle one of their angle is 90 degrees. so, 90 + y + 2y = 180

3y = 180 - 90 = 90

y = 90/3 = 30 then 2y = 2×30 = 60 degrees

so, angles are 90, 60, and 30 degrees

3. i) 40degrees as they are corresponding angles

ii) alternate interior angles.

4. i) 90 degrees

ii) BC = BN + NC = 5 cm + 5 cm = 10cm as BN and NC

are equal.
