Answer:
B. DE = 58
Step-by-step explanation:
The base angles (<F and <E) of the ∆DEF are congruent/equal. This means that ∆DEF is an isosceles triangle.
This implies that, the two sides (DF and DE) that are opposite to the base angles are congruent/equal.
DE = 40 (given) => option B is INCORRECT
Therefore:
8x - 24 = 40
Solve for x
8x - 24 + 24 = 40 + 24
8x = 64
8x/8 = 64/8
x = 8 (option C is CORRECT)
Let's find DF and FE:
DF = 8x - 24
Plug in the value of x
DF = 8(8) - 24
DF = 64 - 24
DF = 40 (Option D is CORRECT)
FE = 6x + 10
FE = 6(8) + 10
FE = 48 + 10
FE = 58 (Option A is CORRECT)
The only incorrect statement is:
B. DE = 58
Answer:
Step-by-step explanation:
Let the shorter side be x
Then the longer side is x + 1
<u>Perimeter is:</u>
- P = 2( x + x + 1) = 2(2x + 1) = 4x + 2
The value of perimeter is at most 60 meters. P ≤ 60.
<u>Solve the inequality:</u>
- 4x + 2 ≤ 60
- 4x ≤ 58
- x ≤ 58/4
- x ≤ 14.5
Since x is the integer, its greatest value is 14 m
