Geometry, Finding angles and solving for X

OpenStudy (anonymous):

# 10 and 19, I really appriciate it :D

OpenStudy (anonymous):

Let's see for #10: This figure is a parallelogram, which means opposite angles are the same. (3a + 50) = 104 3a = 54 a = 54 / 3 = 18.

OpenStudy (anonymous):

Awesome, I get it, so 19?

OpenStudy (anonymous):

Oh yeah, 19, I can't see the figure completely. Can you post the figure completely?

OpenStudy (anonymous):

yup

OpenStudy (anonymous):

thanks

OpenStudy (anonymous):

FE is 12 right? That makes DE 12 too, which makes FE 24.

OpenStudy (anonymous):

those arent any answer options a. ED = 12; FD = 24 b. ED = 8; FD = 20 c. ED = 16; FD = 28

OpenStudy (anonymous):

a. ED = 12; FD = 24 b. ED = 8; FD = 20 c. ED = 16; FD = 28 Those the options

OpenStudy (anonymous):

Oh. I said FE = 24, but that should be FD = 24. DE = ED, the way in which one writes the letters doesn't matter a lot. So a) is the correct answer.

OpenStudy (anonymous):

GOT IT THANKS
