Find the measure of angle X in the figure below Choices: 35°, 47°, 73°, 78°
Answers
Answer:
To find angle x we must first find y
For angle y
Angles on a straight line add up to 180°
56 + 51 + y = 180
y = 180 - 56 -51
y = 73°
Now for angle x
Angles in a triangle add up to 180°
y + x + 72 = 180
y = 73°
73 + x + 72 = 180
x = 180 - 73 -72
x = 35°
Therefore angle x is 35°
Hope this helps.
First, it's worth noting that angles on a straight line sum to 180°. We can use this information to find out the value of y:
180-52-59=69
y=69°
Another rule is that the angles in a triangle sum to 180° as well. This means that we can now find out x:
63+y+x=180
63+69+x=180
180-63-69=x
x=47°

Answer:
Eric's father works for 5 hours in the afternoon
Step-by-step explanation:
Eric's father works two part time jobs, one in the morning and one in the afternoon, and works a total of 40 hours each 5-day workweek.
Step 1
The number of hours he works each days is calculated as:
40 hours÷ 5days
= 8 hours per day.
Hence, he works 8 hours per day.
Step 2
We are told in the question that:
If his schedule is the same each day, and he works 3 hours each morning, how many hours does Eric's father work each afternoon?
The total number of hours in works in a day = Number of hours worked in the morning + Number of hours worked in the afternoon
Hence:
8 hours = 3 hours + x
x = 8 hours - 3 hours
x = 5 hours
Therefore, Eric's father works for 5 hours in the afternoon

Answers
Answer:
A (5-7)^
Step-by-step explanation:
We have the next two functions h(x)=x-7 and g(x)=x^. We need to find (g•h) that is equal to g(h(x)) then:
(g•h)=g(h(x))=(x-7)^
Finally in the poin x=5 we have:
(g•h)=g(h(x))=(x-7)^
(g•h)=g(h(5))=(5-7)^
Then the answer is A
(g•h)(5) means that you need to solve g(h(5)). So, you plug 5 in for x in h(x), then you plug the solution of that in for x in g(x) like so:
The answer is A. (5-7)²
