School bus : 9 tons = 9*2000 = 18,000 pounds
Horse : 1,100 pounds
Elephant : 5,500 kilograms = 5,500*2.2 = 12,100 pounds
Grand piano : 15,840 ounces = 15,840/16 = 990 pounds
So the answer is
a) Here, sum of two non-adjacent angles: 52 + 25 = 77
Now, ∠3 = 180 - 77 [ sum of all angles in a triangle is 180 ]
so, ∠3 = 103
Now, ∠3 + ∠4 = 180 [ Supplementary angles ]
So, ∠4 = 180 - ∠3
∠4 = 180 - 103 = 77
∠4 = 77 [ which is sum of two non-adjacent angles ]
....Hence proved.
b) m∠4 = 77
[ Solved in previous section ]
