Answer:
30
Step-by-step explanation:
Because there are infinitely many numbers that are either greater or less than variable x.
12x+7+6x-7=90
12x+6x=90
18x=90
x=5
6(5)-7=
30-7=23
Q=23
Answer:
C
Step-by-step explanation:
We're given the adjecent and we're looking for the hypotenuse so we'll have to use cosine ratio.
11 / cos 38 = 13.959.....
x = 14.0
We can also use the tangent ratio to look for the opposite and then use pythagorean to find the hypotenuse.
11(tan 38) = 8.594......
8.594.....² + 11² = 194.859......
Square root of 194.859..... = 13.959.......
