Answer:
To find < E we use tan
tan E = opposite / adjacent
DF is the opposite
EF is the adjacent
DF = 11
EF = 11
tan E = 11/11
tan E = 1
E = 45

A trapezoid/trapezium is a quadrilateral (4 sided shape) with exactly one pair of parallel sides.
It is a quadrilateral (a closed plane shape with four linear sides) that has at least one pair of parallel lines for sides
The only factors of 73 are itself and one so it is a prime number.
Probability of getting an order from Restaurant A or an order that is accurate is 1.21,
The events are not disjoint events.
<h3>
What is the probability?</h3>
Probability is used to calculate the odds that a random event would occur. The odds that the random event happens lie between 0 and 1.
Total number of accurate orders = 332 + 277 + 244 + 150 = 1,003
Total number of orders = 31 + 51 + 30 + 10 + 1003 = 1,125
Total number of orders from restaurant A = 332 + 31 = 363
Probability of getting an order from Restaurant A = total number of orders from restaurant A / total number of orders
363 / 1125 = 0.32
Probability that the order is accurate = number of accurate orders / total number of orders
1003 / 1125 = 0.89
Probability of getting an order from Restaurant A or an order that is accurate = 0.32 + 0.89 = 1.21
Disjoint events are events that are mutually exclusive. If one event happens, the other event cannot happen
