The sum of all of the exterior angles of any regular polygon is 360 (I'm assuming by decagon you mean a regular dodecagon).
Because the total has to be 360, and a decagon has 10 sides, you divide 360 by 10 to get each exterior angle.
360 ÷ 10 = 36, so each exterior angle of a decagon is 36 degrees.
Answer:
h(x-5)=2x-5
Step-by-step explanation:
What we want to do is replacing x-5 with x and we got h(x-5)=2(x-5)+5, using the distributive property and simplify to the simplest expression is going to be h(x-5)=2x-5
