Answer:

15 degreese

Step-by-step explanation:

Given AOB 30 - has to make angle DOB 150 cause that be 180 since DA is the diameter

Also they say DE is the same as EK - 30

now EKA is 180 but you got to subtract that EK 30 = 150

to find C you do 1/2 ( ABD - KA )

1/2 (180 - 150)

is 15

Greetings!

This can be solved by creating a simple equation.
$1/4+1/6+x=1$

Solve for x.
$1/4+1/6+x=1$
Find the LCM.
$3/12+2/12+x=1$
$5/12+x=1$
Add -5/12 to both sides.
$(5/12+x)+(-5/12)=(1)+(-5/12)$
Simplify.
$x=1/1-5/12$
Find the LCM.
$x=12/12-5/12$
$x=7/12$

He kept 7/12 of the raisins for himself.

Hope this helps.
