Which is the best approximation of the perimeter of a right isosceles triangle if it's hypotenuse is 12 units long

Answers

Answer 1

Answer: ok so isocileese
that means that the 2 legs are eual

a^2+b^2=c^2
a=b
c=12
2a^2=12^2
2a^2=144
divide 2
a^2=72
a=6√2

perimiter=a+b+c
a=b
P=6√2+6√2+12
P=12√2+12
P=aprox 28.97 units

Answer:

1st, 2nd and 6th options

Step-by-step explanation:

Given

$(2)/(3)$ - x + $(1)/(6)$ = 6x ( multiply through by 6 to clear the fractions )

4 - 6x + 1 = 36x ← option 1 will have the same solution set

----------------------------------------------------------------------

Adding the 2 fractions on the left side gives

$(4)/(6)$ + $(1)/(6)$ - x = 6x , that is

$(5)/(6)$ - x = 6x ← option 2 will have the same solution set

------------------------------------------------------------------------

From

4 - 6x + 1 = 36x ( add 6x to both sides )

5 = 42x ← option 6 will have the same solution set

To the nearest tenth, what is the length of the hypotenuse of an isosceles right triangle with a leg of 7 3 inches? A) 15.7inches
B) 16.2 inches
C) 17.1 inches
D) 18.5 inches

Answers

Answer:

the answer is the option C

$17.1\ in$

Step-by-step explanation:

we know that

An isosceles right triangle has two equal legs

Let

x------> the length side of the hypotenuse

y-----> the length side of the leg

Applying the Pythagoras theorem

$x^(2) =y^(2)+y^(2)$

$x^(2) =2y^(2)$

In this problem we have

$y=7√(3)\ in$

Substitute and solve for x

$x^(2) =2(7√(3))^(2)$

$x=17.1\ in$
