Answer:

Angles IJG and KJL are vertical angles

Step-by-step explanation:

Vertical angles are formed when two lines intersect. It's a terrible name for them, because the name has nothing to do with the common word "vertica" (up-and-down).

The attached image shows an example of a pair of vertical angles. Another pair is angles AED and CEB.

Make x the subject means you need to solve for x

y = ax^2 solve for x

divide both side by a

y/a = ax^2/a

simplify
y/a = x^2
so
x = square root (y/a)

The value of a professional basketball player's autograph rose 30% in the last year. It is now worth $273.00. What was it worth

serg [7]

$210
because if it rose 30%, it's now 130% of what is used to be
or (what it used to be) ×1.3
so do the reverse and divide the new cost by 1.3
so 273÷1.3 which is 210
