help please there is also another question i asked like 7 hours ago that was NEVER ANSWERED but please answer ILL MARK BRAINLIES
eduard

Answer:

the first one would be m<EOF+m<FOB=180°,

and the second one would be 76ft

Step-by-step explanation:

supplementary angle means the angle that would make it equal 180°. if m<EOF is an acute angle then the angle that is supplementary to EOF would be obtuse, so FOB.

then for the second question, the midpoint splits the angle in HALF, so that means in order to find RT you multiply 38×2.
