The scientist can use only the angle x and the distance y to calculate the distance between the Earth and the Sun using the cosine function.
cos x = BC / y
Solving for BC
BC = y cos x
BC is the distance between the Earth and the Sun :D

step by step explanation:
Jake brought a car = 1500rs
Jake sell the car = 1800
profit = sp-cp
so profit = 1800-1500 = 300
profit percent = gain/cp×100
profit percent = 300/1500×100
profit percent = 20% (double zero are cancel and 300 divided by 15)
