Please help!!! Trigonometry is so complicated to me
Eva8 [605]

Answer:

x = 4

Step-by-step explanation:

Given that sin(13x) = cos(9x+2)

Since sintheta  = cos(90 - theta)

hence sin (13x) = cos (90 -13x)

Substitute into the original equation

cos (90 -13x) = cos(9x+2)

90-13x = 9x+2

-13x - 9x = 2 - 90

-22x = -88

x = 88/22

x = 4

Hence the value of x is 4

If two sets are disjoint, then what region represents the union of their complements in a Venn diagram?
katrin [286]
If 2 sets are disjoint means they have not any common element.

Draw a rectangle & inscribe inside this rectangle 2 circles that do not intersect.

cercle₁ ∩ cercle₂ =Ф.
Their complement would be the part of the rectangle - the 2 circles
