Answer:
School X has 8 points and School Y has 2 points
Step-by-step explanation:
From first sentence
X - 6 = Y
From second sentence
X = 4Y
Hence substitute equation 1 into equation 2
4Y - 6 = Y
Y = 2
X = 4 x 2 = 8
Answer:
12
Step-by-step explanation:
It is worthwhile memorizing the ratios of legs in a 30°–60°–90° triangle. Shortest to longest, the ratios are ...
1 : √3 : 2
Then the sides marked will have the ratio ...
6 : x = 1 : 2 = 6 : 12
x = 12
_____
You can also get there using trigonometry.
cos(60°) = 6/x
x = 60/cos(60° = 60/0.5
x = 12
