Answer:
ok
Step-by-step explanation:
2. It's an obtuse triangle . Because the third angle is 105 degrees.[180 - (35+40) = 180- 75 = 105degrees]
3. let the percentage be x . then,
₹63 × x% = ₹90
4. the longest chord = diameter amnd diameter = 2 × radius
hence, radius = 10cm / 2 = 5cm
5. The longest chord in a circle is called its diameter.
The diameter is the double of radius
6. 8 angles.
