Answer:
-3
Step-by-step explanation:
since the 9 in negative you subtract 9 by 6 and you get 3 then you put the negative sign in front of the 3 making it -3
If you divide on a calculator, you get 4.468208092, so I would say the answer is 4.4, since the number after 4 is 6, which is more than 5, I round to the 4. Hope this helps!
Aye Sir!
Remark
You are dealing with a right angle triangle. You can use one of Sin(x) Cos(x) or Tan(x). Since the Hypotenuse is involved and since you are given the adjacent side, Cos(71) is what you will need.
Solution
H = BC
Cos(x) = adjactent / hypotenuse
Cos(71) = 6.3 / H Multiply both sides by H
H * Cos(71) = 6.3 Divide by Cos(71)
H = 6.3 / cos(71) Cos(71) = 0.32557
H = 6.3 / 0.32557 Divide
H = BC = 19.351 Answer
Answer:
<h2>x=-0.3</h2>
Step-by-step explanation:
1-(-7.2x+3.5)=5+3(7.4x-1) first parenthesis
1+7.2x-3.5=5+22.2x-3
7.2x-2.5=2+22.2x (x on one side and numbers on other)
22.2x-7.2x= -2-2.5
15x=4.5 divide by 15
x=-4.5/15
<h2>x=-0.3</h2>
