To find the third side of a triangle (there are two answers you could get), you need to use the Pythagorean formula: a^2+b^2=c^2. First answer, 3^2+5^2=c^2. Solve for c. c=5.83. The second answer, 3^2+b^2=5^2. Solve for b. b=4.
Answer:
x = 40
Step-by-step explanation:
collect the terms (3-2)x = 40
subtract the numbers 1x = 40
divide from both side 1x/1 = 40/1
solution x = 40
This is the answer graphed but it is x>-2

40.249 rounded would be 40.2
