Answer:
a = 33ft
b= 66ft
c = 48 ft
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
- a (shortest side)= a
- b (second side)=2a (twice the length of the shortest side)
- c (third side)= a+15 ( 15 feet more than the length of the shortest side)
Since:
Perimeter = a+b+c
Replacing with the values given:
147 = a+2a+(a+15)
147 = a+2a+a+15
147-15 = a+2a+a
132 = 4a
132/4 = a
33 ft= a
Substituting a =33 in the other expressions:
b=2a = 2(33) = 66 ft
c= a+15 = 33+15 = 48 ft
Answer:
2, 3, 5, 6
Step-by-step explanation:
because the angles are outside
Answer:
6(x+2)=66
6x+12=66 -12
6x= 54 :6
x=9

wait check b4 you answer
Answer:
a=14
Step-by-step explanation:
if a=10, 10/2 = 5 plus 9 = 14
