Question

Find the measures of the angles.

m∠ADE

m∠DEC



A.
m∠ADE = 58°

m∠DEC = 135°

B.
m∠ADE = 58°

m∠DEC = 125°

C.
m∠ADE = 68°

m∠DEC = 125°

D.
m∠ADE = 68°

m∠DEC = 135°

Answer 1

i dont really understand

Answer 2

\[\angle AED + \angle DEC = 180^{o} ( AC \ is \ a\ straight \ line )\]
since you know the value of AED .... u can find DEC from here..
\[\angle ADE = \angle EDC = 90^{o}\]
from here u can find EDC..

can u do that ?
