Geometry triangles plz helpp

Okay for every triangle, the degrees have to add up to 180 degrees. For example, the triangle that has c,h and 92 degrees, have to add up to 180, which means you can subtract 92 from and 180 and you’ll get 88, and since you need to find out both C and H you can divide 88 by 2 and you’ll get 44, which therefore C and H equal 44! Now try to solve the rest!

Iwould think that the correct answer is 8.1
