Answer:
x = 48
Step-by-step explanation:
equation:
180 - x = 132
subtract 180 from each side:
180 - 180 - x = 132 - 180
-x = -48
divide both sides by -1:
x = 48
to check, substitute 48 for x:
180 - x = 132
180 - 48 = 132
132 = 132
In triangle EFG,
EG = 4.8 units
Since angle FDE = angle FED,
EF = FD = 3.5 units [sides opposite to equal angles]
FG = DE = 3 units [Given]
s = (a+b+c)/2
= (EG+EF+GF)/2
= (4.8+3.5+3)/2
= 11.3/2
now using Heron's formula,
area of EFG =
Lilly's age = x
Hillary age = 19 years old
Hillary age <span>is 3 years greater than 2/3 times Lilly's age =
2/3x + 3 = 19
2/3x = 16
x = 16 * 3/2
x = 24
answer
Lily is 24 years old</span>
