Question

Please help asap what is the measure if angle D i degrees

Answer 1

55 degrees

Explanation:

Since the triangle must equal 180 degrees,

180 - 83 - 42 = 55

Answer 2

D = 55

Explanation:

The sum of the angles of a triangle is 180 degrees

B+C+D = 180

83+42+D = 180

Combine like terms

125 + D = 180

Subtract 125 from each side

125+D - 125 = 180-125

D =55
