ΔTXV is an <span>isosceles triangle because ∡T = ∡X therefore TV = VX.
3x - 24 = 2x + 1 |subtract 2x from both sides
x - 24 = 1 |add 24 to both sides
x = 25

Hi there!
~
cosec 20 -cot 40= 1/sin 20 - cos 40/sin 40
= (sin 40 -cos 40 sin20)/(sin 40 sin 20)
= 1/sin 40 ( 2 cos 20 - cos 40)
=1/sin20 ( 2 cos(60-40)-cos 40)
=1/sin40( 2 cos 60 cos 40 - 2 sin 60 -sin 40-cos 40)
Put the value of cos 60
= 1/sin 40 ( 2 sin 60 sin 40)
=root(3)
Hope this helped you!
2x - y = 1
y = 2x -1
slope = 2
perpendicular slope = -1/2
y = mx + c
y = -1/2 + c
at point (3,2)
2 = -1/2 (3) + c
c = 2 + 3/2
c = 7/2
y = -1/2 x + 7/2
y + 1/2x = 7/2
2x - y = 1 ------------------- (1)
y + 1/2x = 7/2 -------------(2)
(1) + (2):
2x + 1/2x = 1 + 7/2
5/2 x = 9/2
5x = 9
x = 9/5 ---- sub into (1)
2x - y = 1
2(9/5) - y = 1
18/5 - y = 1
y = 18/5 - 1
y = 13/5
Ans: x = 9/5, y = 13/5
