Answer:

$\displaystyle 36\:units$

Step-by-step explanation:

Split up this Isosceles, Right Triangle into two congruent smaller right triangles. The reflexive side [the line that splits them apart] is 6 units, and both legs are 8 units, leaving the hypotenuses to AUTOMATICALLY be 10 units, according to the Pythagorean Theorem:

$\displaystyle a^2 + b^2 = c^2 \\ \\ 6^2 + 8^2 = 10^2 \\ \\ 36 + 64 = 100 \\ \\ 100 = 100$

With this Pythagorean Triple, we know that our dimensions are correct. Now, to find the perimeter, just add up all the sides EXCEPT for the divider:

$\displaystyle 2[10] + 2[8] = 20 + 16 = 36$

HELP ME PLAESE ASAP PLAESE TELL ME HOW YOU SOLVED ITT

I believe it is 960 inches. For the long triangles, I just made them a square so I multiplied base times height. For the small triangles, i did the same thing. Long triangles were 640, small triangles were 320

Answer: x=20°

Explanation: Since UTX is a diameter, it is equal to 180°. You can now set up the equation (4x+2)+x+78=180. Then solve for x.

You should get, x=20.

Simplify 425xy⁴/25xy²

beks73 [17]

We have the expression

$\frac{425xy^4}{25xy^2}$

We can already simplify x because it's both on the numerator and denominator

$\frac{425y^4}{25y^2}$

Now we can simplify 425/25 = 17

$\frac{17y^4}{y^2}$

Remember that

$\frac{a^n}{a^m}=a^{n-m}$

Then

$17y^{4-2}=17y^2$

The final result is

$17y^2$
