The incenter of a triangle is the center of its inscribed circle. <span>Generally, the easiest way to find the incenter is by first determining the </span>inradius and then<span> each side of the triangle can be </span>translated<span> by the length of the inradius, We also can use coordinate geometry through this formula:
Step-by-step explanation: so multiply 3 by 10. Then subtract 10 from both sides so you should be left with 20=5r and then you divide both sides by 5 to equal 4
