Question

find x lines and angles
​

Answer 1

Answer:

In triangle ABC <ACB is 90 degree

<CAB is 40 degree

THerefore by angle sum property of a triangle i.e, sum of all angles of a triangle is 180 degree ..

so <ABC = 180 - 90 + 40

<ABC = 180-130

<ABC = 50 degree

now in triangle  EBD <EBC = 50 and < BED = 100

therefore x=180-100+50

x= 180-150

x= 30 degree

Answer 2

Answer:

x=30°

Step-by-step explanation:

we know,

ABC is a right angle triangle.so, angle acb= 90 °

therefore,

angle bac+ angle+ acb+ angle acb =180°

40°+90°+angle acb=180°

angle acb=50°

now,in triangle edb,

100+50°+x=180°

x=30°
