Answer:
8 and 1/6 units²
Step-by-step explanation:
Answer:
1. D. ray PS
2. C. angle GFE
3. A. 30 deg
Step-by-step explanation:
1. To name a ray, use two points on the ray. The first point must be the endpoint. The second point can be any point on the ray.
ray PS and ray PT are both correct.
Choose D. ray PS
2. Two ways of naming an angle are: 1. Use just the vertex point. 2. Use three points: a point on one ray, the vertex, a point on the other ray in that order.
This angle can be named:
angle EFG
angle GFE
angle F
Choose C. angle GFE
3. Angles CBE and ABD are vertical angles. Vertical angles are congruent. They have the same measure. Since angle ABD measures 30 deg, then angle CBE also measures 30 deg.
Choose: A. 30 deg
The sum of all five numbers in the list is 25.
According to the question,
The first number on my list of five numbers is 1, and the fifth is 5. The other figures are all one more than their two nearest neighbors' averages.
Let the list of numbers be 1,x,y,z,5.
As each of the other numbers is equal to one more than the average of its two neighbors.
x=(1+y)/2+1
2x=3+y -(1)
Similarly,
y=(x+z)/2+1
2y=x+z+2 -(2)
z=(y+5)/2+1
2z=y+7 -(3)
Multiply equation (2) by 2 and then substitute equations (1) and (3),
4y=3+y+y+7+4
4y=2y+14
2y=14
y=14/2
y=7
From equation (1),
2x=3+7
2x=10
x=5
From equation (3),
2z=7+7
2z=14
z=14/2
z=7
The list is: 1,5,7,7,5
Sum of the numbers of list = 1+5+7+7+5 = 25
