Answer:
it is right triangle so we have trigonometric ratio: tan(54)=3/x and from that we have x=3/tan(54)
C
Step-by-step explanation:
I took the test
12x+4-16x = 0
-4x + 4 = 0
-4x = 0-4
x = -4/-4
x= 1
a. 1 b. 3/5 or 60%
number of favourable events/number of total events
3x/5x = 3/5
1 3/4d= 14
7/4d = 14
d = 8
Hope this helps! ;)
