Try this Drag ... Alter the number of sides. ... If you know the apothem, or inradius, (the perpendicular distance from center to a side.
Missing: 6.8 | Must include: 6.8
Step-by-step explanation:
9x+15+6x+24x=39x+15 ...i first distrubuted 3 to the parantheses
The common difference is 2
The distributive property is a(b + c) = ab + ac
Answer:
Step-by-step explanation:
To prove Δ ABC similar to ΔDBE we can consider
Segments AC and DE are parallel.
⇒ DE intersects AB and BC in same ratio.
AB is a transversal line passing AC and DE.
⇒∠BAC=∠BDE [corresponding angles]
Angle B is congruent to itself due to the reflexive property.
All of them are telling a relation of parts of ΔABC to ΔDBE.
The only option which is not used to prove that ΔABC is similar to ΔDBE is the first option ,"The sum of angles A and B are supplementary to angle C".
