Question

Suppose right triangle ABC has one acute angle 47º. Suppose also that right triangle DEF has an acute angle 43º. How are triangles ABC and DEF related?

Answer 1

their both triangles.
And i'm guessing yo mean triangles with a 90 degree corner as well.
Triangles ALLWAYS have 180 degrees in total.
If on corner is 90 degrees there is only 90 left and if one also is 43 degrees the one left is 47 as 90-43=47 and vica versa.
