For parallelogram LMNO, if angle L=4x-25 and angle N=3x+18, find angle M

1 answer:

3 0

L=N (because opposite angle of parllalogram is euqal)

4X-25= 3X+18
X =43

there for angle N=3×43+18
N=147

Now we know that the sum of the corresponding angle of a parllalogram is 180
N+M=180
M=180-147

M=33

Answer:

Step-by-step explanation:

Given, 

m || n

So,

35° = y° [Alternate interior angles]

And,

y° + x° = 180° [Since linear pair]

=> x + 35 = 180

=> x = 180 - 35

=> x = 145°

Hence, 

x = 145°, y = 35°

leonid [27]

Answer:

B. 10/91

Step-by-step explanation:

Box has 5 red buttons and 9 blue buttons.

We add 5 and 9 to get the total buttons.

5 + 9 = 14

Then, we find the probability for a red button.

5/14 = .35

Now, that we've taken out 1 button.

The amount of buttons available changes.

14 - 1 = 13

There are 4 red buttons remaining.

The probability for a red button changes to 4/13.

4/13 = .30

Then, we multiply both probabilities.

.30 x .35 = .111

Convert to a fraction.

.111 = 10/91

Thus it would be B.
