Answer:
No.
Step-by-step explanation:
Both sets contain the elements k and m.
Answer:
A)
– 6x – 2x = 16
-8x = 16
x = 16/-8 = -2
B)
3(3x – 6) = 18
9x - 18 = 18
9x = 18 + 18 = 36
x = 36/9 = 4
C) ASSUMING YOU MADE AN ERROR BY WRITING 0 INSTEAD OF (
5(2x + 3) =-4(-5 – 2x)
10x + 15 = 20 + 8x
10x - 8x = 20 - 15
2x = 5
x = 5/2
12x =
The answer for number 4 is 13 and number 6 is 121 and the last problem for number 7 is 112
Answer:
22.62°
Step-by-step explanation:
Looking at the attached diagram, it is a right angled triangle. If we are to solve for the measure of angle x , we would be using the Trigonometric function of cosine
The formula is given as
cos x = Adjacent/ Hypothenuse
Adjacent = 12
Hypothenuse = 13
Therefore,
cos x° = 12/13
x° = cos -¹ (12/13) or arccos (12/13)
x° = 22.619864948°
Therefore, the measure of x to the nearest hundredth = 22.62°
