It should be 100 because it has to add up to 180 and 50+30=80 so the third angle must be 100
Hey there Gary!
If Angle DBC is 73, you do subtract it from 180 to get ABD.
180 - 73 = 107
Angle ABD = 107
Angle DBC = 73
Angle ABD > DBC
or
Angle DBC < ABD
The line BD/DB is the same length in both angles, proving line AD is greater than CD. This is also justified by the fact that lines AB and CB are congruent.
I hope this helps, let me know if there's something wrong about my answer.
Half of perimeter (or length+ width) is:
222 mm /2= 111 mm.
111 mm- 60 mm= 51 mm
The width of the rectangle is 51 mm~
Answer:
Step-by-step explanation:
3/4 and 2/5 have a common denominator which is twenty so you can rewrite the equation with just knowing that
You can then multiply both sides by twenty to solve this equation.
Hope this helps.
