ray bd bisects angle abc. what are the measures of angles; abd, cbd, and abc? the equations are 3x+6 and 7x-18.

7 answers

Given:
ABD = 3x+6.
CBD = 7x-18.

ABD = CBD. The bisector divides an angle into 2 equal angles.
3x+6 = 7x-18. Substitution.
X = 6.

ABD = 3x+6 = 3*6+6 = 24.
CBD = 7x-18 = 7*6-18 = 24.

ABC = ABD + CBD. = 24+24 = 48.

In D abc,A=54.21 B=71.51 a=12.4 cm find a

lol. idk. Do your work 🤪
