Question

Find m/_DEC
37
61
82
98

Answer 1

61

Step-by-step explanation

The sum of the triangle is 180

because they give you the measurement of the triangle connected to DEC you can calculate the measurement of ∠DCE which is 82

now you take the sum which is 180 and subtract 37 and 82

180 - 37 - 82 = 61
