Question

2. The distance between the points (a cos 25°, 0) and (0, a cos 65°) is
(a) a
(b) 2a
(c) 3a
(d) None of these​

Answer 1

Answer:

(d) none of these

Step-by-step explanation:

apply distance formula,

let A = ( a cos 25° , 0) B = ( 0, a cos 65°)

AB = √ ( x1-x2)^2 - ( y1-y2)^2

Answer 2

Answer:

a is a answer

Step-by-step explanation:

The distance between the points (a cos 25°,0) and (0, a cos 65°) is - YOUR ANSWER SOLUTION Distance between given two points = v(a cos 25° – 0)2 + (0 – a cos 65°)2 = a(V cosa 25° We know that, cos a = sin(90° – a) *
