Answer:
∠ACB = ∠DFE
Step-by-step explanation:
In SAS postulate,
S refers to Side.
A refers to Angle.
In the triangles, △ABC and △DEF,
AC = DF ( Side )
CB = FE ( Side )
The additional information required to prove is <u>Angle</u>.
Angle between sides AC and CB in △ABC and Angle between sides CB and FE in △DEF respectively.
Angle between sides AC and CB is ∠ACB.
Angle between sides CB and FE is ∠DFE.
So according to SAS postulate,
∠ACB = ∠DFE
Answer:
90
Step-by-step explanation:
Think of 5(18) as 5(10+8). This is easily done mentally: 50 + 40 = 90.
The answer is "D".
x+x+(x+11)+(x+11)=86
4x+22=86
subtract 22
4x=64
divide by 4
x=16
Answer:
Esmeralda has enough music left in her playlist for a 30 minute workout
Step-by-step explanation:
we know that
If Esmeralda accidentally deleted 25% of the music, then the percentage of music left in her playlist equals 100%-25%=75%.

Find out how many minutes represent 75% of 40 minutes
Multiply 40 by 0.75

therefore
Esmeralda has enough music left in her playlist for a 30 minute workout
