Yes
If they form 90 degrees, they are perpendicular
Answer:
9 cm
Step-by-step explanation:
If you were to imagine this right triangle, you would find it to be a 45 - 45 - 90 triangle. Perhaps the " shorter leg " piece of information was present to trick you, considering that the legs are congruent by converse to base angle theorem.
How is this triangle a 45 - 45 - 90? In such a triangle, the legs can be posed as x cm, as the base angles are congruent ( 45 and 45 ), thus the legs of the triangle are congruent as well. The hypotenuse would be x√2, and as we can see -
If legs = x, Hypotenuse = x√2 = 9√2
Thus, the length of the other leg is 9 centimeters ( 9 cm )

Answer:
y = 4
Step-by-step explanation:
First isolate y
-4 + 3y = 8
3y = 8 + 4
3y = 12
y = 4
So we need to factor it into (ax+b)(cx+d)
since we have 1x^2, a and c=1
so factor into (x+b)(x+d)
if we expand, we get
![(x+b)(x+d)=x^2+(b+d)x+bd](https://tex.z-dn.net/?f=%28x%2Bb%29%28x%2Bd%29%3Dx%5E2%2B%28b%2Bd%29x%2Bbd)
so we need 2 numbers that add to get the middle number and multiply to get the last number
I would factor the last number and see which ones add to the middle one
what 2 numbers multily to get 72 and add to get 17?
hmm, list factor of 72 and add them
1+72=73, nope
2+36=38, nope
3+24=27, nope
4+13=17, yep
so it facotrs to (x+4)(x+13)
Answer:
1 /8
Step-by-step explanation:
Given that :
Number of sections on spinner = (1,2,3,4,5,6,7,8) = 8
Number of 5's = 1
Recall :
Probability of event A = number required outcome / Total possible outcomes
P(5) = 1/8
