measure angle c + measure angle b=180 (Since opposite sides of a parallelogram)75 + d=180Therefore d=180-75Therefore d=105 Reply

Answer: 105degree Step-by-step explanation: because adjacent angles m 180degree if we add them therefore 75+x= 180 x=180-75 x=105 so m angle b is 105degree Reply

measure angle c + measure angle b=180

(Since opposite sides of a parallelogram)

75 + d=180

Therefore d=180-75

Therefore d=105

Answer:105degree

Step-by-step explanation:because adjacent angles m 180degree if we add them

therefore

75+x= 180

x=180-75

x=105

so m angle b is 105degree
