Answer:
12m
Step-by-step explanation:
To find the area of the rectangle we multiply l by w
so
lw=a
if l=2+w we can substitute l with 2+w
so now
w(w+2)=168
distribute
w^2+2w=168
Now we use guess and check to solve
13^2 is 169
so 12^2 is 144 and 2*12=24
and 144+24=168

i cant understand that ppic
Answer:
a = c because they are vertical angles. vertical angles are alway congruent because they are bascially the same shape. it's a rule.
We know that,
Sum of the angles in linear pair is 180°.
Given,
Angle 1 and Angle 2 are Linear Pair of Angles.
So,
Angle 1 + Angle 2 = 180°
=> 65° + Angle 2 = 180°
=> Angle 2 = 180° - 65°
=> Angle 2 = 115°
So, Angle 2 = 115°.
