The total weight of all boxes is 140 kg. To form 130 kg, we would need to exclude a 10 kg box, which doesn't exist. Thus, 130 kg is impossible.

Question 16

In triangle ABC, ∠ABC = 15o .D is a point on BC such that AD = BD. What is the measure of ∠ADC (in degrees)?

Accepted Answer

Since AD = BD, triangle ABD is isosceles, making ∠DAB = ∠DBA = 15°. The exterior angle ∠ADC equals the sum of interior opposite angles: 15° + 15° = 30°.

Question 17

If 6 * 9 – 4 = 58 and 3 * 9 – 7 = 34, then in the expression A * 4 – 9 = 91, what is the value of 'A'?

If Tan θ = 9/40, then Sec θ = ?

Accepted Answer

Tan θ = 9/40 means Perpendicular = 9, Base = 40. Hypotenuse = √(9² + 40²) = 41. Sec θ = Hypotenuse / Base = 41/40.
