Question

In the figure, ABCD is a square, MDC is an equilateral triangle. Find
the value of x.
(A) 75°
(C) 105°
(B) 90°
(D) 60°​

Answer 1

Answer:

105°

Step-by-step explanation:

∆MDC is an equilateral triangle. therefore all the angles will be 60°.

angle MCB=BCD-MCD

=90-60 = 30°

NOW,

In ∆BCD,

BC=CD

Therefore angle XBC = 45°.

when angle sum is applied in ∆CBX, X=105°

Answer 2

Answer:

B 90 is the correct answer
