Answer 1

Answer:

Distance between given points will be d=

(acosθ−0)

2

+(0−asinθ)

d=a

Answer 2

THIS IS THE ANSWER TO UR QUESTION PLS MARK ME AS BRAINLIEST

Step-by-step explanation:

we have acc distance formula √(x²-x1¹)²+(y²-y¹)²

x¹=cos theta

x²=sin theta

y¹=sin theta

y²=-cos theta

√(sin+cos)²+(cos+sin)²

=√1+1

=√2
