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

Answer:
Step-by-step explanation:
15x+10x=12x+90; ⇔ 13x=90;
Answer: Its 11.31 or
Step-by-step explanation:
So the distance formula is d=√((x_2-x_1)²+(y_2-y_1)²).
Point A is (-2,2) and Point B is (6,-6).
So then we replace the numbers
d=√(6+2)²+(-6-2)²
d=√(8)²+(-8)²
d=√64+64.
d=√128.
d=11.31
