Tan9°. tan27°. tan45°. tan72°. tan81°= 1 could u plz solve it with clear process

Inga [223]

Correct question:-

Prove that tan9.tan17.tan45.tan73.tan81=1

LHS

$\\ \sf\longmapsto tan9.tan17.tan45.tan73.tan81$

$\\ \sf\longmapsto tan9.tan81.tan17.tan73.tan45$

$\\ \sf\longmapsto tan(90-81).tan81.tan(90-73).tan73.1$

$\\ \sf\longmapsto cot81.tan81.cot73.tan73$

$\\ \sf\longmapsto 1.1$

$\\ \sf\longmapsto 1$

Sati [7]

Year 3 = 2s

x = first year

2s = 26

s = 13

The second year they made 13 million

13 - 3 = 10

x = 10

They made 10 million the first year.

What are the rate of changes for

astraxan [27]

39 & 16.5 = -22.5
30 & 12.4 = -17.6
28 & 10.4 = -17.6
19 & 10.3 = -8.7
23 & 11.2 = -11.8
if the values are y values you will subtract them from each other to get the numerical value and because they all go from a larger number to a smaller number the rate is a negative. if they were from a smaller value to a larger value teh rates of change would be positive.
