The answer is 65 because when you add 35+65+15 you get 115 and a triangle is 180 degrees so<span> 180-115=65</span><span>
</span>
Step 2: it should be P-2x, not +.
Hope this helped :)
Answer:
, 8cm, are both options
Step-by-step explanation:
For a right triangle one can find the length of the longest side by using the Pythagorean theorem. So there are two options I can think of that if the triangle is a right triangle will work. First remember what the Pythagorean theorem is : side a^2+side b^2=hypotenuse^2
The hypotenuse is the longest side of a right triangle. So if the sides that are 15 and 17 cm are not the longest sides then the formula would be:

But if 17cm is the longest side then:

The period of a sinusoid

is

, so any range such that

will give two complete periods.
If we're talking in whole numbers, the only multiplication of whole numbers that equals two is
2 * 1
or
-2 * -1
