Cade and Tyce both tried to find the missing side of the right triangle. A right triangle is shown. The legs are labeled 6 and 9
Talja [164]

Step-by-step explanation:

Two legs of the right triangle are 6 and 9. We can find its third side as follows :

a^2+b^2=c^2

The above is called Pythagoras theorem and it is applicable for a right angled triangle.

a,b and c are base, perpendicular and hypotenuse respectively

c is the third side

So,

c^2=6^2+9^2\\\\c=\sqrt{117} \\\\c=10.816\approx 10.82

Hence, Cade and Tyce both are correct. The length of the missing side is 10.82

Answer:

b

Step-by-step explanation:

In y=mx+b form, the b is the y-intercept, therefore where the line crosses the y-axis on the graph. In this graph, the line crosses the y-axis at 100. This means that the "b" value is 100. So far, our equation is y=mx+100.

Next, to find m, you go to any other point on the graph and see how much units (rise over run) you went to get there. I picked the point (2,150), You can see that it took me 1 unit up and 2 units to the right to get to that point, leading us to believe the slope is 1/2.

Finally, put everything together and you get the answer of y=1/2x+100 (the letters do not matter) :)
