Question

find the unknown angles : X, Y and Z degrees ​

Answer 1

Answer:

X=90 degree, Y=40 degree & Z=50 degree

Solution:

For Z:

<ACD+<DCA=180

Or, <ACD+130=180

Or, <ACD=180-130

Or, <ACD=50

For Y:

<ABC+<EBC=180

Or, <ABC+140=180

Or, <ABC=180-140

Or, <ABC=40

For Z:

<ABC+<ACB+<BAC=180

Or, 40+50+<BAC=180

Or, <BAC=180-90

Or, <BAC=90

Answer 2

Answer:

z = 50° y=40°

Step-by-step explanation:

z = 180-130=50°

y=180-140=40°
