Question

find X value from the following diagram

Answer 1

this is the answer of question that you are tagged in. find the value of the x in triangle .this is solved by exterior angle property.

Answer 2

Answer:

65°

Step-by-step explanation:

to solve the answer first we take ∆ ABC

the sum of triangle is 180°

i.e.angle A + angle B + angle C = 180°

75°+55°+angle C = 180°

130°+ angle C = 180°

angle C = 180°-130°=50

now in line BCD

the sum of linear line is 180°

i.e. angle BCA + angle ACE+ angle ECD=180°

50°+35°+ angle ECD= 180°

85° + angle ECD = 180°

angle ECD= 180°-85°=95°

now in ∆ ECD,

angle E + angle C + angle D= 180°

x+95°+20°=180°

x+115°=180°

x=180°-115°=65°
