Answer:

The answer to your question is π radians

Step-by-step explanation:

Data

degrees = 180°

radians = ?

Process

To find the answer just need to memorize the proportion.

Always 2π ⇒ 360° or π ⇒ 180°.

Then

2π radians ----------------- 360°

x ----------------- 180°

x = (180° x 2π) / 360°

-Simplifying

x = 360°π / 360°

-Result

x = π radians

Please help me gow to this bro , im confused

Ok so remember that a circle is 360 degrees and a line is 180 degrees
so

IKJ
ok so we see that we have a triangle
to find the internal angles (which add to 180)
we do, opposite angles are equal
JIK=59
also CJI+KJI=180 so 132+KJI=180, KJI=48
so
59+48+IKJ=180
73=IKJ

HIB
we can assume that AB is paralell to CD
so therefor IJK=HIB=48 (from previous question)

EIJ is adding to EIH to get 180
EIJ+59=180
EIJ=121

AIK=AIJ+JIK
JIK=59
AIJ=HIB=48
AIK=59+48=107

IKJ=73
HIB=48
EIJ=121
AIK=107
