Answer:
6.7
Step-by-step explanation:
cos(48) = adjacent/hypotenuse
cos(48) = x/10
x = 10cos(48)
x = 6.691306064
Answer:
Step-by-step explanation:
Answer:
B
7 less than 3 times a number (X) is (3x-7), and then the sum of these two numbers means we have (3x-7)+X, and then we know this equals 109, leaving us with:
(3x-7)+x = 109
x² - 4x - 12 = 0
Factor the left side: (x + 2) · (x - 6) = 0
The equation is true if either factor is zero.
If (x + 2) = 0 then x = -2 .
If (x - 6) = 0 then x = 6 .
