Question

find 'x' value in the figure
step by step plz ​

Answer 1

Answer:

In triangle ABE,

Using angle sum property,

100+30+A=180°

130°+A=180°

A=180°-130°=50°

So, angle A=50°

Now, In triangle ABC,

Using angle sum property,

A + B+C=180°

50°+30°+x+20°+65°=180°

165°+x=180°

x= 180°-165°

x= 15°

Step by step explanation given.

Answer 2

Answer:

Given,

ABC is a triangle

angle ABE = 30⁰

angle AEB = 100⁰

Angle DBC = 20⁰

angle DCB = 65⁰

Angle BDC = 180 - angle DBC + angle DCB (sum of angles of a triangle = 180⁰ , DBC is a triangle)

= 180 - 20 + 65

= 180 - 85

= 95⁰ = angle BDC

angle BDE = 180 - 95 (AC is a straight line)

angle BDE = 85⁰

angle BED = 180 - 100 (AC is a straight line)

angle BED = 80⁰

x = 180 - 80 + 85 (sum of angles of a triangle is 180⁰)

= 180 - 165

x = 15⁰ is the answer
