During the 2005 football season team tackle the team sack by eight points if the combine scores total of 26 find the individual
Ierofanga [76]

Answer:

Team sack = 9

Team tackle = 17

Step-by-step explanation:

To start with, we'd assume that

Let x = the points scored by Team Sack

Let x + 8 = the points scored by Team Tackle

x + x + 8 = 26

So, go further and solve mathematically

2x + 8 = 26

if we subtract 8 from both sides, we have

2x = 18

Next, we then divide both sides by 2. So that,

x = 18/2

x = 9

Since we assumed the total points for Team Sack to be x, then Team Sack scored 9 points while Team Tackle scored x + 8 points, and that is 17

Can someone help me with #69
alex41 [277]
Ok, so you have a right angle, a given angle, and a given side for the left triangle. We are going to call angle 47° angle A. So angle A=47°, the side connecting the two triangles is directly opposite A making it side "a". We are calling the right angle C and the hypotenuse (the longest side which is 11) "c".  So, Sin A=a/c and since we don't have "a" we multiply both sides by "c" changing it to (c Sin A)=a. 11•Sin(47°)=a

11•(0.7313537016)=a
