Question

Determine the measures of angle ACB, angle DCE, & Angle BCD.

Answer 1

Answer: ∠ACB= 60°, ∠DCE= 65°, ∠BCD= 55°

Explanation:

1) Since ΔABC is an equilateral, we know ∠ACB= 60°

2) Since we know ΔCDE is an isosceles, we know that ∠DCE= 1/2 (180-50), which is 65°

3) We can add the 2 angles and then subtract them from 180 degrees to get ∠BCD= 55°
