Answer:
∠ADB = γ/2 +90°
Step-by-step explanation:
Here's one way to show the measure of ∠ADB.
∠ADB = 180° - (α + β) . . . . . sum of angles in ΔABD
∠ADB + (2α +β) + γ + (2β +α) = 360° . . . . . sum of angles in DXCY
Substituting for (α + β) in the second equation, we get ...
∠ADB + 3(180° - ∠ADB) + γ = 360°
180° + γ = 2(∠ADB) . . . . . . add 2(∠ADB)-360°
∠ADB = γ/2 + 90° . . . . . . . divide by 2

To find angles CXD and CYD, we observe that these are exterior angles to triangles AXB and AYB, respectively. As such, those angles are equal to the sum of the remote interior angles, taking into account that AY and BX are angle bisectors.
The expression (1/2)[x+10] represents the one half of the sum of a number and 10.
It is defined as the combination of constants and variables with mathematical operators.
We have:
One half of the sum of a number and 10
Let's suppose the number is x:
So from the problem, the one half of the sum of a number and 10 is:
The above expression represents the one half of the sum of a number and 10.
Thus, the expression (1/2)[x+10] represents the one half of the sum of a number and 10.

A line graph would best represent the temperature changes throughout the hours of a day, showing a slow increase in the morning, a sharp rise at noon, a plateau in the afternoon, and a slight decrease at night.
The best graph to represent the temperature changes throughout the hours of a day would be a line graph. The graph should show a slow increase in temperature early in the morning, a sharp rise at noon, a plateau during the afternoon, and a slight decrease as night falls. This pattern follows the circadian rhythm, where temperature rises throughout the waking day, peaks in the afternoon, and falls during sleep.
#SPJ2
Answer:
Temperature changes throughout the hours of a day. Early in the morning, temperature increases slowly. At noon, the temperature rises sharply. During the afternoon, the temperature stays the same for several hours. As night falls, the temperature decreases slightly. Choose the graph that best represents this situation,
