Answer:
The proved is given below.
Step-by-step explanation:
Given ABCD is a parallelogram and also ∠ABE equals 180°, ∠CBE ≅ ∠CEB
We have to prove that ∠DAE ≅ ∠CEA
As ∠CEA=∠CBE → (1)
and given ABCD is a parallelogram implies AD||CB
∴ ∠DAE=∠CBE → (2) as these are corresponding angles.
From equation (1) and (2), we get
∠DAE=∠CEA
Hence, ∠DAE is congruent to ∠CEA
Hence Proved
Answer:
115
Step-by-step explanation:
5\color{red}{x}+\color{blue}{168}=
5x+168=
\,\,\color{purple}{743}
743
-\color{blue}{168}\phantom{=}
−168=
\,\,-\color{blue}{168}
−168
Subtract 168 from both sides
5\color{red}{x}=
5x=
\,\,575
575
\frac{5\color{red}{x}}{5}=
5
5x
=
\,\,\frac{575}{5}
5
575
Divide both sides by 5
\color{red}{x}=
x=
\,\,\boxed{\color{red}{115}}

20p-by-step explanation:
The correct answer is the last option
So
a. so 100-1/10 of 100 or 100-10=90
then second dose minus 10% or 90-9=81
third dose 81 minus 10%=81-8.1=72.9
fourth dose 72.9 minus 10% or 72.9-7.29=65.61
so after 4th dose only 65.61% are left
b. so to get it to 5% you do alot and find that it takes 27 tries to get the percent down to 5.2% and 28 doses to get it to 4.7%
