Answer:
The answer is below
Step-by-step explanation:
We need to prove that:
(Root of Sec A - 1 / Root of Sec A + 1) + (Root of Sec A + 1 / Root of Sec A - 1) = 2 cosec A.
Firstly, 1 / cos A = sec A, 1 / sin A = cosec A and tanA = sinA / cosA.
Also, 1 + tan²A = sec²A; sec²A - 1 = tan²A
In order for something to be a function, it has to pass the vertical line test, atleast in the standard coordinate plane. This is because a single x value can’t correlate with two separate y values. So the first one is not and the second one is
We know that 100paise=1 rupee
=>500 paise = 5 rs
ratio =5/20=1/4=1:4
hope it helps :)
plz mark as brainliest
Slope= -3/2
Y-intercept=33/2
For 3, it is an isosceles triangle and it is an acute triangle.
