Question

Please help me solve this!!​

Answer 1

Answer:

A) 40

Step-by-step explanation:

A RHOMBUS IS A PARALELLOGRAM, ANGLE PQS AND RSQ ARE ADJACENT HENCE ADD UP TO 180,

AND THESE TRIANGLES PQR AND SQR ARE CONGRUENT,

THEREFORE X=80/2=40

OR

IN TRIANGLE QRS ,

ANGLE S =100

ALSO QS=RS,

THEREFORE AS TWO SIDES ARE EQUAL THE OPPOSITE ANGLES ARE ALSO EQUAL,

HENCE 80/2 =40=X
