Question

Work must be shown for this problem! The figure shown below is a rectangle. *

Answer 1

Explanation:

Diagonal of rectangle are equal and bisect each other.

So CE = EB

Angles opposite to equal sides are equal.

Therefore, ∠ECB = ∠EBC

∠ECB = 61

In ΔCEB,

∠ECB + ∠EBC + ∠CEB = 180 {sum of angles of triangle}

61 + 61 + ∠CEB = 180

122 + ∠CEB = 180

∠CEB = 180 - 122

∠CEB = 58°
