Question

Given LG is the diameter, calculate the measurement of angle AU.

Answer 1

what is AU here?

Answer 2

I just attached the file @shubham0109

Answer 3

that's why I need help on finding the arc of AU *not angle my bad*

Answer 4

x=26.29
2x=52.58
arc AU=angle 2x (in radians) * (lg/2)[the radius]

Answer 5

how did you get 26.29? and 52.58?

Answer 6

sum of all the angles equals 360 degrees

Answer 7

I know a whole circle is 360..I still dont know how you got that.
Also "arc AU=angle 2x (in radians) * (lg/2)[the radius]" idk how to do this
do i have to plug in something?

Answer 8

that's a formula
you have to convert 52.58 degrees into radians(1 deg=3.14/108) and then multiply it by the radius

Answer 9

4x+2x-14+2x+3x+10+74.8=360
that's how you find x
and then multiply it by 2 to get 2x(your angle in degrees)

Answer 10

oh ok..thank you
