For (1), in geometry, when angles are vertically opposite, they are said to be equal. If one angle is 2x and the vertically opposite angle is x + 30, then we can equate them.
For (2), we will need to consider where each angle is located in relation to each other.
Vertically opposite angles are equal.
Two angles that make up a right angle are complementary. (two angles that add up to 90)
Angles in the same segment of a straight line with another line cutting the straight line are supplementary (such as angles COD and AOD) These two angles add up to 180
He coud walk 5 meters in one hour because i did 60-12-12-12-12 and then you have a extra 12 so he got 5 meters in one hour part b he can 1 more further because 1 meter because before it was 12 hope explained it right
Step-by-step explanation: 0.59 is 59%. To find the percentage of chance that it will not rain, you subtract 1 (which is 100%) minus 0.59. You get an answer of 0.41 (or 41% if you prefer.)
