Question

find the value of x and y give solution ​

Answer 1

Answer:

in the first diagram

x = 60°

y= 50°

in the second diagram

x= 45°

y= 45°

Step-by-step explanation:

IN THE FIRST DIAGRAM,

GIVEN : angle BAC =70° ,

angle ABC = x,

angle ACB = y,

angle BCD = 130°

angle ACB + angle BCD = 180° ----(angles in a

linear pair)

y + 130° = 180° -----( from given)

[y = 50°] ----------(equation 1)

angleABC +angleACB+angleBAC = 180°

----( addition of all angles of a triangle is 180°)

x + y + 70° = 180° ------( from given)

x + 50° +70° = 180° ----(from equation 1)

x+ 120° = 180°

[x =60°]

therefore in diagram 1

x= 60° and y = 50°
