Answer: 10/36
When a pair of fair dice are rolled , the total possible cases are (6 × 6) = 36. Out of these 36 cases the following 10 cases are favors(giving the sum > 8) for the happening of the event . These 10 cases are (3, 6), (4, 5), (4, 6),(5, 4), (5, 5), (5, 6) , (6, 3), (6, 4), (6, 5), & (6, 6)
Given information:
A fence on a hill uses vertical posts L and M to hold parallel rails N and P
The diagram is attached below
Here lines N and P are parallel lines
Transversal line for parallel lines N and P is line L
Calculation:
angle 1 and angle 16 are consecutive exterior angles
If parallel lines are cut by a transversal then consecutive exterior angles are supplementary.
<em><1 +< 16 = 180</em>
<em>115+ < 16 = 180</em>
<em>< 16 = 180 - 15</em>
<em>< 16 = 65</em>
<em />
<em>So measurement of angle 16 = 65 degrees.</em>
<em></em>
Unknown side = (25^2-5^2)^.5 = 24.5
Using the Pythagorean theorem
