Question

Find the value of x,
(Geometry, Will give medal)

Answer 1

We know from a theorem that a straight line always gives us a straight angle, meaning that any point I take from it wil have an angle of 180º.
So, no matter how many angles I have if they are between two points I know are alined, then their sum must be 180º.

Si, in the drawing we have the angle x, a right angle and a angle of 67º.
But since I know they all must sum up to 180º, then I can write it mathematicalltçy:
\[x+90º+67º=180º\]
and all you have to do is solve for x.

Answer 2

x=23?

Answer 3

Correct!

Answer 4

thank!
can you help me with 2 other problems similar to this one? this section in my geometry class im really struggling with!

Answer 5

Sure, that's why I'm here.

Answer 6

its finding the value of x again.

Answer 7

Are those the angles?, the drawing is pretty messy.

Answer 8

its a jpeg from my practice test. so i assume that they are angles.

Answer 9

Okay, Do you know how many degrees a full circle has?

Answer 10

360.

Answer 11

Good, so all those four angles must sum up 360º.
so writing it mathematically:
\[x+(x+3)+(x+10)+(x+1)=360º\]
simplifying:
\[4x+14=360º\]
And all you have to do i solve for x

Answer 12

i got 86.50

Answer 13

that's correct, not many times will angles with an "x" give you a whole number.

Answer 14

Crap, i have answers to choose from, which are
A. 1/2
B. 3/4
C. 2
D. 4
now im super confused..

Answer 15

@Owlcoffee

Answer 16

are you sure those were angles?

Answer 17

i think its 1/2

Answer 18

yep i was right. thanks for the help.! i did the last one on my own and i understand the concept a lot better thank you!
