If you are examining a triangle with given measurements for one leg and the hypotenuse, how will you determine the measure of th
horrorfan [7]
You will use a2+b2=c2 (squared).The leg will represent the a2 or either b2 and the hypotenuse will be the c2.After filling in the variables you will then subtract the a2 which is the leg from the c2 which is the hypotenuse.And then you will factor it or square root it.If you square root it and it’s not a feasible answer then use the Christmas tree or birthday cake method to factor the answer and then you’ll have the value of b2 which is the unknown leg.

Can anyone help me please?
Grace [21]

Answer: 17

Step-by-step explanation:

We can tell that for every 2 changes in X there is 8 points lost in y

meaning that if we do 8 /2 we get 4

Every 1 change in x there is 4 points of change in Y

so if (3,5) Then (0,17)

17 - 5 = 12 And 3-0 = 3 So for 3 points of change for Xthere were 12 points of change for Y so this is right
