Assuming you are given a standard form equation, you should convert it to vertex format. If you are given root equation form, you would have to convert to standard form.
Assuming you have;
ax²+bx+c=y
a(x²+b/ax)+c=y
a(x²+b/ax+(b/2a)²-(b/2a)²)+c=y
a(x²+b/ax+(b/2a)²)+c-a(b/2a)²=y
a(x+b/2a)²+c-a(b/2a)²=y
Try to use this format to solve the problems.
Hope I helped :)
Answer:
12
Step-by-step explanation:
His original number was 8 because if you subtract 7-23=16 then 16/2=8
The two angles are 30 degrees and 60 degrees
<em><u>Solution:</u></em>
Given that,
The measures of two complementary angles have a ratio of 1 : 2
Let the one of angle be 1x
Let the other angle be 2x
We know that,
Sum of two complementary angles is 90 degrees
Therefore,
1x + 2x = 90
3x = 90
Divide both sides by 3
x = 30
<em><u>Therefore, measure of each angles is:</u></em>
One angle = 1x = 30
Other angle = 2x = 2(30) = 60
Thus the two angles are 30 degrees and 60 degrees
