What is the value of [tex] x [/tex] in triangle BCD if angle B is 91 degrees, angle C is 33 degrees, and angle D is [tex] x [/tex] degrees?

A. 56
B. 66
C. 124
D. 236

Answer :

Final answer:

The value of x in triangle BCD is 56 degrees. Hence, option A is the correct answer.

Explanation:

To find the value of x in triangle BCD where angle B is 91 degrees, angle C is 33 degrees, and angle D is x degrees, we can use the fundamental property of triangles: the sum of the interior angles in any triangle is always 180 degrees. Therefore, to find x, you can use the following formula:

x = 180 - (angle B + angle C)

By substituting the given angle measures into the formula:

x = 180 - (91 + 33)

x = 180 - 124

x = 56 degrees

So, the value of x is 56 degrees, which corresponds to option (a).
