-3+8x-5=-8 solve for x
Scrat [10]
Do you have any options? If not, try going with this method to help you understand this problem a little bit better :) Here we go! 

-3 + 8(x) - 5 {-8} = ? 

8(x) = ? You have to solve this to make it more "easier" if that makes sense
             
              From the looks of it you have to divide by the number, which we call 8

Since, we have only one solution in this problem, the value of "x" is 0 
x  = 0 

And not all one solution problem(s) always equal "0". .. it can equal any number sometimes 

Good Luck!

Can someone help with these trigonometry problems

4. What you want to do is first find the tan ratio, because tangent is opposite / adjacent, which you can use to find x.

So tan(52) = 1.28 ish. So we know that x/18 = 1.28.
Then multiply both sides by 18.

x / 18 * 18 = 1.28 * 18

x = about 23.

5. Now, you can use the pythagorean's theorem, a^2 + b^2 = c^2.

Just input all values.

18 ^ 2 + 23 ^ 2 = c ^ 2

324 + 529 = c ^ 2

853 = c^2

square root of 853 = c

x = 29.2 ish

6. In this case, use cosine, or adjacent / hypotenuse.

cos(16) = 0.96 ish

so that means 24/x = 0.96

Then basically,

24 / 0.96 = x

x = 25

So x = 25

Then you can use the Pythagorean's Theorem again. I'm not going to go as in depth.

a ^ 2 + b ^ 2 = c ^ 2

24 ^ 2 + b ^ 2 = 25 ^ 2

576 + b ^ 2 = 625

b ^ 2 = 49

b = 7

8. Use tan here. opposite/adjacent Again, not going as in depth.

tan(55) = 1.43 ish

1.43 = Y / 22

1.42 * 22 = Y

Y = 31.24 ish

Length of MN:

31.24 ^ 2 + 22 ^ 2 = c ^ 2

976ish + 484 = c ^ 2

1460 = c ^ 2

x = 38.2 ish

10. Use cosine.

cos(63) = about 0.45

Adjacent / hypotenuse

3 / x = 0.45

3 / 0.45= x

x = 6.67

And then pythagorean's Theorem.

6.67 ^ 2 = 3 ^ 2 + b ^ 2

44.5 = 9 + b ^ 2

35.5 = b^2

b = about 6
