Answer:
it is isosceles triangle with an angle = 90. Two others angle are equal. sum of all angles in triangle is 180.
2x + 90=180 --> x=45
Answer:
Scale Factor is: When you divide the old shape by the new shape (explanation is here)
Step-by-step explanation:
When you have 2 shapes (lets say Y is the old shape and F is the new shape) you would divide the old shape (Y) by the new shape (F)
Another example: lets say shape F is 12 cm and shape Y is 7 cm (F being the old and Y being the new shape) you would divide 12 and 7 to get the answer to that problem
Answer:
Step-by-step explanation:
I'm going to presume you want this linear equation in slope-intercept form, so start with:
Subtract 
from both sides of the equation:
Subtract 
from both sides of the equation:
Divide both sides of the equation by the coefficient of 
, which is 
:
Simplify:

Answer: y = 12/(x^2)</h3>
============================================================
Explanation:
"y varies inversely as x^2" means y = k/(x^2) for some constant k.
Plug in (x,y) = (2,3) and solve for k
y = k/(x^2)
3 = k/(2^2)
3 = k/4
3*4 = k
12 = k
k = 12
The original equation updates to y = 12/(x^2)
As a check, plugging in x = 2 should lead to y = 3
y = 12/(x^2)
y = 12/(2^2)
y = 12/4
y = 3 ... we get the proper y value, so the answer is confirmed.
