(8•40) + (8•5) = 320 + 40 = 360
Answer:
x = 5.5
Step-by-step explanation:
Using a trig ratio, you can use sin, which is opposite over hypotenuse. 
Now, multiply both sides by 11

this simplifies to x =
or 5.5.
Since sin30 is
radians, it can be written as
.
Square root of 25/16 is 5/4
square root of 36/25 is 6/5
square root of 25/16 - square root of 36/25 = 5/4 - 6/5 = (25 - 24)/20 = 1/20
