Answer:5 + /- sqrt35
Step-by-step explanation:
Rearranging, we get x^2 -10x -10=0
Applying the quadratic formula,
(10 +/- sqrt(10^2 -4*-10))/2
(10+/- 2sqrt35) /2 = 5 + /- sqrt35 as the two roots.

Answer:
y = 1/2x-1/2
Step-by-step explanation:
y = mx+b is the slope intercept form of a line
where m is the slope and b is the y intercept
y = 1/2x +b
We can substitute the point (3,1) in for x and y
1 = 1/2(3) +b
2/2 = 3/2 +b
2/2 -3/2 = b
-1/2 =b
y = 1/2x-1/2
This is because the total needs to be equal to 180 degrees. Since obtuse angles are greater than 90 degrees, then it needs an acute angle (lower than 90 degrees) to supplement it to equal 180
