Statement:
1. RS tangent to Circle A and Circle B at points R and S
2. AR ⊥ RS, BS ⊥ RS
3. AR ║ BS
Reason:
1. Given
2. Radius ⊥ to tangent
3. 2 lines ⊥ to same line are ║
100% Correct
~Hope it helps~ :)
Your answer would be choice b
Step-by-step explanation:
Hi, I think correct variant is B
(28÷7)+7=4+7=11
T = 0
=> Q = 0
t = x
=> Q = arcsin(x/a)
rest it just simple integration of trigonometric function
