4x = 2x + 30 Alternate angles in parallel lines are equal
2x = 30
x = 15
Answer:
10. x = 7√2
11. x = 9, y = 18
12. x = 6√2
13. x = about 11ft
14. x = 8
15 3,4,5
Step-by-step explanation:
10. pythagorean theorem a^2 + b^2 = c^2
11. it is a 30, 60, 90 triangle; since 9√3 is across from the 60 degree angel, we know that the length across from 30 is 9. And the length across the right angle is double the one across the 30 degree angle.
12. pythagorean theorem
13. trigonomotry, (sine, cosine, tangent), you want to find the angle that is next to the right angle. to find that angle you do cosine of 4 and 12 (cos^-1 = 4/14). Next, you find x, you use sine of 71 times 12. When you plug it in it should look like this = 12sin(71 .
14. it is a 3,4,5 triangle x = 8 because it is double 4
15. because it is
Answer:
2 goals
Step-by-step explanation:
After 5 games the team scored 1.8*5=91.8∗5=9 goals.
After 6 games the team scored 9+3=129+3=12 goals.
The mean after 6 games is \frac{12}{6}=2
6
12
=2 goals.

Answer:
and 
Step-by-step explanation:
The first answer you are just adding 4 and 1/4. The second answer you are adding a negative number with a postive fraction so you get a negative fraction.
