Question

□ ABCD is a
parallelogram.
mLc = 75° then mLb =
​

Answer 1

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

Answer 2

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
