Answer:
Step-by-step explanation:
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°.
Answer:
if im thinking correctly the answer will be y=34x+5
Step-by-step explanation:
have a brilliant day and be sure to smile!(:
Minus 9x from both sides
-3y=-9x+12
divide both sides by -3
y=3x-4
square ?
although this statement doesn't make any sense.
