The answer is unlikely, there is a 2 out of 30 percent chance.
Answer: 1.5
Step-by-step explanation: Reverse the equation to get the answer.
-13 divided by 2 is -6.5
add 8 and you'll get 1.5
Just did a specific one of these; let's do the general case.
The point nearest the origin is (a,b).
The line from the origin through the point is

The line we seek is perpendicular to this one. We swap the coefficients on x and y, negating one, to get the perpendicular family of lines. We set the constant by plugging in the point (a,b):


That's standard form; let's plug in the numbers:


SO you know that triangles add up to 180. A right angle equals 90 so 180-90=90. And an isosceles triangle means that 2 angles are congruent. SO 90/2 = 45. The measure of the 2 acute angles are 45
