Hey there,
Ok so we need to put this into slope-intercept form so we can find the slope eaisly, (y=mx+b)
If we move x to the right side we are left with,
2y=-x-3
Next we divide by 2 to free up the y,
y=-1/2x-3/2, this is now in y=mx+b form. Making the slope -1/2
Hope this helped!
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

Answer:
165 ways
Step-by-step explanation:
Selection deals with combination
There are a total of 11 from which 3 are to be selected
11C3 = 11!/3!(11-3)!
= 11!/(3!x8!)
=(11x10x9x8!)/(3x2x8!)
=11x10x9/6
=11x5x3 = 165 ways
