Answer:

y=(1/2)x -3

Step-by-step explanation:

Simplify equation:

4x+2y=10

2y= -4x+10

y= -2x+5

Insert coordinates (trying to find b) (perpendicular lines have opposite reciprocal slopes) :

-1= (1/2)(4)+b

-1=2+b

-3=b

Insert b and new slope to equation:

y=(1/2)x -3

Using a straightedge draw a random triangle now carefully cut it out next amputate the angles by snipping through adjacents side

Nezavi [6.7K]

This is usually used as a proof that triangles have 180°. Look at the attached figures. If you cut off angle A, angle B and angle C and rotate them so that their vertices touch, you form a half-circle out of them (or a straight line). We know that half a circle is 1/2 of 360° or 180; therefore all 3 angles in a triangle must add up to 180°.
