Question

3. FIND THE MEASURE OF <X AND <Y .IS TRIANGLE CDE ISOSCELES? IF SO NAME ITS EQUAL SIDES.​

Answer 1

Step-by-step explanation:

y+130°=180 (linear pair)

y=180-130

y=50°

In ∆ CDE

angle C + angle D + angle E = 180° (angle sum property)

40°+x+y =180°

40°+x+50°=180°

90°+x = 180°

x=180°-90°= 90°

NO, THE TRIANGLE CDE IS NOT A ISOSCELES TRIANGLE.

BECAUSE ITS SIDES ARE NOT EQUAL.

CD≠CE

hence,x=90° and y= 50°
