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
3.4 is a rational number, because it is not a repeating decimal
The answer is
A. 1
B. 25
C. 10
D. -2
Answer:
about 3.0 meters
Step-by-step explanation:
30-60-90 triangle rules:
smallest side is half the hypotenuse
the longer side of the 90 degree is the short side times sqrt of 3
Th answer is 16 becase if u just divide 224 and 14 you will have the aswer and i just did the math for you
