given the diagram of parallelogram lmno, find measurement of angle m

a.
15°
b.
25°
c.
60°
d.
90°

60 degrees

Step-by-step explanation:

Given is a parallelogram LMNO

Angles are given as 4r , 3t-1, 3s and 2t+10

Since in a parallelogram opposite sides are parallel, we have

sum of adjacent angles =180:

4r+2t+10 =180 ... i

Also opposite angles equal

Hence 3t-15 = 2t+10

t =25

Substitute this

in angle M = 3t-15

=3(25)-15

=60

=====================================

explanation

the graph has a slope of 1/3 because each time you move up 1, you go to the right 3. so, slope = rise/run = 1/3. we can cross choice a off the list since we want a slope of 3, rather than 1/3.

the first table shown has a slope of -3. this is because the rise is -6 and the run is 2, so slope = rise/run = -6/2 = -3. note how x increases by 2 each time (run) and y drops by 6 each time (rise). choice b can be eliminated.

the second table has a slope of 3. each time x goes up by 1, the y values increase by 3. slope = rise/run = 3/1 = 3. alternatively you can use the slope formula to prove that the slope is 3 here. use any two rows of values to generate the two points. choice c is one of the answers

the third table also has a slope of 3. let's use the slope formula to prove as such. i'm going to use the first two rows of the table. so i'll use the two points (2,1) and (5,10)

m = slope

m = (y2-y1)/(x2-x1)

m = (10-1)/(5-2)

m = 9/3

m = 3 so we get a slope of 3

choice d is the other answer

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
