Answer:

32 degrees

Step-by-step explanation:

Because the triangle is isosceles, 2 of its angles must equal each other:

15x - 31 = 9x + 11

---> x = 7

Plug 7 into either 15x - 31 and 9x + 11:

15(7) - 31 = 74 degrees

and

9(7) + 11 = 74 degrees

Add them together, and you get 148 degrees.

Finally, subtract 180 from 148 to get 32 degrees for angle S.

What is the length of the hypotenuse of the triangle below?

Vedmedyk [2.9K]

Answer:

Step-by-step explanation:

So here we have a 45-45-90 triangle.

This a special right triangle were the sides across from the 45 degree angles can be considered x, while the hypotenuse is two square roots of x.

Here since we have the sides across from the 45 degree angle we can conclude that $x = 9\sqrt{2}$

So if we wanted the hypotenuse we would just plug in this value of x like so:

$hyp = x\sqrt{2} \\$

$hyp = (9\sqrt{2})(\sqrt{2})$

$hyp = 9(2)\\$

$hyp = 18$

Therefore the hypotenuse is 18.

hodyreva [135]

The answer is 9 because the difference in this sequence goes +1,+2,+3 etc. So all you have to do is plus 6 to 15 and you get 9.
