Angle1 +angle2+angle3=180(property of triangle)
Angle1+angel2=angle3(according to question)
Thus,
Angle3+angle3=180
2*angle3=180
Angle3=90
Means this is a right triangle
Now,we can use formula
Side1^2+side2^2=side3^2
Thus,
4*4+5*5=side3^2
Square root(36)=side3
Side3=6
Depends on what you are asking
Y = Mx + c
Finding the equation of the line
Which is y = -3x + 8
Or for finding y
Y = 8-3x
Or if u wanna find x
You subtract y from both sides
3x = 8 - y
Dividing both sides by 3
3x/3 = 8/3 -y/3
Which leave 8 -y divided by 3
First you would have to multiply 12 times 5 (60) then multiply 7 times 18 (126) you subtract both [ 126 - 60] = (66) that would be your final answer. They both need to have worked 66 minutes to have the same number of boxes.
