Answer:

C° = 71.6056

Step-by-step explanation:

Law of Cosines: c² = a² + b² - 2abcosC°

Step 1: Plug in known variables

29² = 30² + 15² - 2(30)(15)cosC°

Step 2: Evaluate

841 = 900 + 225 - 900cosC°

-59 = 225 - 900cosC°

-284 = -900cosC°

71/225 = cosC°

cos⁻¹(71/225) = C°

C° = 71.6056

And we have our answer!

How do i put 10-5y=3x in y=mx+b form​
irina1246 [14]
Step 1: Rewrite equation

10-5y=3x

Step 2: To get y alone on the left side, subtract 10 on both sides

10-5y=3x
-10 -10
__________
-5y=3x-10

Step 3: divide -5 on both sides, again to get y alone

-5y=3x-10
/-5 /-5 /-5
________
y=-3/5x+2


Final equation: y=-3/5x+2

Hope this helps :)
