Take one angle as 2x and the other as x because then their ratio would be 2:1. And when you add them you get 90. So you want to find x,
2x+x=90
3x=90
x=30
One angle is 2*30 or 60 degrees, and the other is 1*30 or 30 degrees.
And it makes sense. 60:30 is a 2:1 ratio if you divide both sides by 30 and they both add to 90.
Hope this helps.
A= 2bh/1-2h idk of I’m right or not
3x-5=1
+5 +5
3x=6
3 3
X= 2
Answer:
60 °F
Step-by-step explanation:
The function can be put into vertex form:
T(x) = 0.264(x² -18x) +81 . . . . factor the leading coefficient from 1st 2 terms
Now, we add the square of half the x-coefficient inside parentheses and subtract the same quantity outside parentheses.
T(x) = 0.264(x² -18x +81) +81 -0.264·81
T(x) = 0.264(x -9)² +59.616
The low temperature for the day was approximately 59.6 °F, which rounds to 60 °F.
