In parallelogram ABCD, the measure of < C is represented by 3a-10 and < D = a + 80. Find the degree measure of < D. A) 7.5 degrees

B) 100.5 degrees

C)107.5 degrees

D) 187.5 degrees

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)

good luck on ur quiz test or homework. have a good day : )

lr = 24

step-by-step explanation:

note that p is the midpoint of lr. to find the measurement of lr, set the equation:

lr = lp + pr

plug in the corresponding numbers to the corresponding variables:

lr = (15) + (9)

simplify:

lr = 24

24 is your measurement of lr.
