Answer:
1. x=74
2. x=86
Step-by-step explanation:
1. the sum of interior angles in a triangle is 180 degrees
81 + 25 + x = 180
106 + x = 180
x = 74
2. once again the sum of interior angles in a triangle is 180 degrees so add up the terms and set them equal to 180
x + x-35 + 43 = 180
add up like terms (x and x, -35 and 43)
2x +8 = 180
2x = 172
x = 86
Let x = Craig's time
Let y = Tom's time
Create a system of equations to solve this problem.
8 = x + y
y = 4x
Substitute 4x into the y variable in the first equation.
8 = x + 4x. Combine like terms
8 = 5x. Divide each side by 5.
1.6 = x
