Given the following cofunction sin(x - 3)° = cos(2x + 6)°, what is the measure of the smaller angle
Dmitriy789 [7]

Note :

sin(x) = cos (90-x)

Therefore,

sin(x-3) = cos(90-(x-3))

90-[x-3] = 2x+6

90-x+3 = 2x+6

3x = 93-6

x = 31-2

x = 29°

Does 4/7 lies between the numbers -3/5 and 3/4
Nesterboy [21]

one way to do this is to convert each fraction to same denominator ( the LCD)

Well we can eliminate -3/5 because its negative so 4/7 is definitely > -3/5.

4/7 = 16/28 and 3/4 = 21/28

so 4/7 < 3/4

Therfore 4/7 does lie between the 2 fractions
