Answer:
The ratio of the length of the side opposite the 30°angle to the length of the side opposite the 90°angle is 1:2.
Step-by-step explanation:
Consider ABC, With 90° angle at B and 30° angle at C.
To find: AB:AC=?
Solution:
AB = perpendicular of the right angled triangle
AC = Hypotenuse of the triangle



The ratio of the sides ,AB:AC = 1:2.
Hence,the ratio of the length of the side opposite the 30°angle to the length of the side opposite the 90°angle is 1:2.
Make sure that you put a line over the 1s on #2
I can not see the fraction on #1
Answer:
x= 1/2
Step-by-step explanation:
First pick a value of

close to

. You should be fine with

.
The linear approximation of

at

is given by

where

is some fixed value close to

. You have

so



The actual value is closer to -0.9709, so the approximation is decent.
