Answer:
d) x = 72°
Step-by-step explanation:
Corresponding Angles: The pair of angles formed on the same side of traversal which crosses two parallel lines is called a pair of corresponding angles.
These angles are EQUAL to each other.
Now, here in the given figure:
The two below lines are parallel to each other.
Also, the line crossing it on the right side forms a traversal.
So angle x and angle with 72 degrees form a pair of Corresponding Angles.
⇒ x = 72°
Hence the measure of angle x = 72°
Answer:
The number 3 is the stem.
The number 4 is the leaf.
Step-by-step explanation:
The Stem and Leaf Plot is a mathematical table used for the graphical representation of a data set. It involves splitting each data value into a stem (typically the first number, on the left) and a leaf (the last number, on the right).
The stem list is used for grouping data value downwards while the leaf values move rightward from its respective stem values and it's used for showing each data value within a group.
Also, the key of a stem and leaf plot is used as a guide on how to read the data set.
For example, the key for a stem and leaf plot is 3|4. Thus, the number 3 is the "stem" and the number 4 is the "leaf."

Answer: 4.64805 pounds of CO₂ was produced
Step-by-step explanation:
Given that;
wattage = 4694 watt = 4694 /1000 = 4.694 kW
time in use t = 10hrs
CO₂ was produced = ?
Total Energy produced = wattage × time = 4.694 kW × 10hrs = 46.95 kWh
we know that 1 kWh produces 0.99 pounds of CO₂
so
46.95 kWh will produce ⇒ 46.95 kWh × 0.99 = 4.64805 pounds of CO₂
Therefore 4.64805 pounds of CO₂ was produced
