2
Step-by-step explanation:
In 30-60-90
The hypotenuse is always the short leg multiplied by 2
So going backward, 4/2 = 2
Answer:
the value of x is 150° because all are 150°
Yes it is also a 50% decrease.
A) x + y = 24
B) x^2 + y^2 = 306
A) x = 24 -y
Then substituting this into B)
(24 - y)^2 +y^2 = 306
576 -48y +y^2 + y^2 = 306
2 y^2 -48y + 270 = 0
x1 = 15
x2 = 9
