Please Solve this Lines and angles question
Kay [80]

Answer:

133°

Step-by-step explanation:

As vertically opposite angles are equal,

< B E D = < F E G

Therefore,

< B E D = 47°

We know that co - interior angles which occur between 2 parallel lines, are added up to 180°.

Given that, < A B E = x

Therefore,

< B E D + < A B E = 180 °

47 + x = 180

x = 180 - 47

x = 133°

Let me know if you have any other questions. :)

Find the value of x. Round to the nearest tenth.! PLEASE HELPP I’ve been stuck on it for HOURS!
barxatty [35]

Answer

63.2 degrees

Step-by-step explanation:

Using law of cosines:  19^2=8^2+14^2-2(8)(14) cos (x)

361=64+196-224 cos(x)

361=260-224cos(x)

101=224cos(x)

divide both sides by 224, which gets you (rounded to 4th decimal place) 0.4509. do inverse cos which gets you 63.2
