Question

question 3 in the given image plz.. and 4,5,6 also

Answer 1

Answer:

Step-by-step explanation:

3. Angle subtended at centre is double than the angle subtended at any other point. 70 = 2*x => x = 70/2 = 35

Also x = y = 35 as angles in the same segment are equal

4. Area of an equilateral triangle = sq root3 a^2/4 = 12 root 3/4 = 3 root 3 cm^2

5. Number of 0 heads = 500 - 275 - 105 = 120

P(0 heads) = 120/500 = 6/25

6. height is given by sq root(l^2 - r^2)

given l = 34 and radius = 32/2 = 16cm

h = sq root(34^2  - 16^2) = sq root(1156 - 256) = sq root(900) = 30cm
