Question

ABCD is a square. Find the value of angle B + angle C + angle D.

PLS HELP​

Answer 1

Answer:

270°

Step-by-step explanation:

We know that each angle of a square is 90° since it is a square and each angle is equal.

So,

∠B = 90°

∠C = 90°

∠D = 90°

Hence,

∠B + ∠C +∠D

= 90° + 90° + 90°

= 270°
