Question

in the given figure angle c a b is equal to 75 degree angle CBA is equal to 70 degree angle c e d is equal to 115 degree find angle CDE​

Answer 1

$\large{\implies{Answer}}$

first we have to find the angle C

A+b+c=180degree

70+75+C=180

145+C=180

C=180-145

$\large{\implies{C=35degree}}$

Angle(ACB)=Angle(DCE) { vertically opposite angle)

35=Angle(DCE)

Using angle sum property :

D+angle(DCE)+E=180

D+35+115=180

D+150=180

D=180-150

$\large{\implies{\green{D=30degree}}}$

Answer 2

Answer:

angle cde -30 ..........
