Step-by-step explanation:
It is arranged for you already.
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:
</span>

Being

side lengths and with

Answer:
Step-by-step explanation:
These are geometric means problems. In the top one, a is the geometric mean as the height for both the smaller triangles inside the big one. Therefore,

The next one has the geometric mean of b, being a part of the smaller triangle on the left and the big triangle as a whole:

Step by step;

25/75
25 to 75
25/75 / 5/5 = 5/15 you can divided that number me more time (divid it by 5/5) which give you your answer of 1:3
