Answer:
use cosine law
x^2 = 543^2 + 543^2 - 2(543)(543cos 128°
solve for x
Step-by-step explanation:
3384 because .88 times 1800 is 1584 and you have to add that to 1800 making it 3384 (or the questions is really easy and its just 1800.88)
Answer:
Divide 9 from both sides.
Step-by-step explanation:
The first step to solving this equation is to add 23 to both sides.
9x - 23 (+23) = 49 (+23)
9x = 49 + 23
9x = 72
The second step is to isolate the x and divide 9 from both sides:
(9x)/9 = (72)/9
x = 72/9
x = 8

3y+14=44
Answer: First step is to subtract 14 from each side
3y = 30 (divide each side by 3)
y = 30/3, y = 10
