Find the values of a and b for which LMNO is a parallelogram

Mathematics
1 answer:
sashaice [31]3 years ago
4 0

Answer:

a = 50, b = 70

Step-by-step explanation:

In a parallelogram, opposite angles are congruent so we can write the following equation to solve for b:

b + 20 = 2b - 50

-b = -70

b = 70

To solve for a:

a + 40 = 2a - 10

-a = -50

a = 50

Zielflug [23.3K]
The original motivation for choosing the degree as a unit of rotations and angles is unknown. One theory states that it is related to the fact that 360 is approximately the number of days in a year.[5] Ancient astronomers noticed that the sun, which follows through the ecliptic path over the course of the year, seems to advance in its path by approximately one degree each day

irinina [24]
Because if there was 45 trials, and u landed on green 9 times...the resulting probability would be 9/45 which reduces to 1/5, not 1/6.

however, if there were 54 trials, and u landed on green 9 times...the resulting probability would be 9/54 which reduces to 1/6.
