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

A straight line equals 180 degrees, so the 3 angles in the picture need to equal 180.

X + 90 + 25 = 180

x +115 = 180

Subtract 115 from both sides:

x = 65

Robbie, has scored 120 so far this season. He has scored all of his points on 1-point extra point kicks and 3-point field goals.
joja [24]

Answer:

39 and 27

Step-by-step explanation:

GIVEN: Robbie, has scored 120 so far this season. He has scored all of his points on 1-point extra point kicks and 3-point field goals. He has made a total of 66 kicks.

TO FIND: How many of each kick has he made.

SOLUTION:

Lets extra point kicks made by Robbie be x

points scored using extra point kick =1

field goal kicks made by Robbie =66-x

point scored using field goal kick =3

Total points scored by Robbie =120

Total points scored are the sum of points scored by extra point kicks and field goal kicks.

1\times x+(66-x)3=120

198-2x=120

2x=78

x=39

total extra point kicks =39

total field goal kicks =66-39=27

Hence Robbie made 39 and 27 kicks of extra point kick and field goal kicks respectively.
