Answer:
30 (.1)=3
or you could do
30×.1=3
you could use either one but I dont know what the person your turning the work in requires the equation to look like
Answer:
8
Step-by-step explanation:
16(³/⁴) =
= (2⁴)(³/⁴)
= 2⁴ˣ³/⁴
= 2³
= 8
60 is 6 times as many as 10, because 60 is 10 times 6.
Answer:
24 and 66degrees
Step-by-step explanation:
Given the equation
cos(8x+18)=sin(−2x+36)
In trigonometry identity, cos theta = sin (90- theta)
The given expression becomes;
sin (90 - (8x+18)) = sin(−2x+36)
sin will cancel out to have;
90 - (8x+18) = (−2x+36)
90-8x-18 = -2x+36
-8x +72 = -2x+36
-8x + 2x = 36 - 72
-6x = -36
x = 36/6
x = 6
Hence the value of x is 6
cos(8x+18) = cos(8(6)+18)
= cos 66
Also
sin(−2x+36)
= sin(−2(6)+36)
= sin(−12+36)
= sin 24
Hence both angles are 24 and 66degrees
