Question

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

Answer 1

Answer:

D = 55

Step-by-step 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

Answer 2

Answer:

55 degrees

Step-by-step explanation:

Since the triangle must equal 180 degrees,

180 - 83 - 42 = 55
