Answer: Angle L = 54 degrees
Step-by-step explanation:
The sum of the angles in a triangle is 180 degrees. This means that
Angle J + Angle K + Angle L = 180 degrees
Looking at the triangle,
Angle J = 5x degrees
Angle K = 2x degrees
Angle L = 3x degrees
Therefore,
5x + 2x + 3x = 180
10x = 180
Dividing the left hand side of the equation and the right hand side of the equation by 10, it becomes
10x/10 = 180/10
x = 18
Therefore,
Angle L = 3 × 18 = 54 degrees

Answer:
The two numbers are 4 and 22.
Step-by-step explanation:
Let the two numbers be x and y. Let y be the smaller number.
x - y = 18
2y + 3x = 74
Solve the first equation for either variable and plug it into the second equation.
Solving for y: x = y + 18
2y + 3(y + 18) = 74
Simplify.
2y + 3y + 54 = 74
5y + 54 = 74
5y = 20
y = 4
Go back and solve for x.
x - y = 18
x - 4 = 18
x = 22
The two numbers are 4 and 22.
Check using both equations.
The difference between 22 and 4 is 18.
Twice the smaller is 8. Three times the larger is 66. The sum of 8 and 66 is 74.
