Question

In the given figure, ABCD is a rhombus. If angle DCA is 25 degrees. Then find the values of x, y and (z - y).

Answer 1

Answer:

x=30, y=30

Step-by-step explanation:

In △ABC, sum of three angle = 180

angle DCA = angle CAB = x

angle BCA = angle CAD = y

for, rhombus ABCD sum of four angle = 360

(x+y)+120+(x+y)+120=360

2x+2y=360−120−120

2x+2y=120

x+y=60

only answer A is follow the equation x+y=60

so, the answer is A.
