Answer:
b = 15°
Step-by-step explanation:
The base angles (c = ∠QRP) of ΔQPR are such that the sum of angles of the triangle is 180°. Since the triangle isosceles, the base angles are equal:
2c +60 = 180
2c = 120
c = 60 . . . . . . degrees; the base angle of ΔQPR
__
Likewise, the base angle (∠SRP) of ΔSPR is ...
a = (180 -90)/2 = 45 . . . . . degrees
__
The measure of angle b is the difference between the larger and smaller base angles:
b = c -a = 60° -45°
b = 15°
B because opposite rays are two rays that both start from a common point and go off in exactly opposite directions
Answer:
C = (36/3)* $24
C = $288
Step-by-step explanation:
In this question, we are asked to write an equation for cost c of the section of fence needed for the garden and the solve for the value c.
C is already assigned as the cost of the sections she needs for her garden.
We were made to understand that the perimeter of the garden is 36 feet, with a 3 feet each section. Now, what we need to do is to know the number of sections that we have. Since, each section is 3 feet, and the total perimeter is 36 feet, this means that the total number of sections needed would be 36/3. Each of the section as we were told costs $24, so we can then proceed to calculate the value of C from there.
C = (36/3)* $24
This is the equation that gives the cost. The actual value of the cost is thus:
C = 12 * 24 = $288
The total cost of the sections if the Fence is $288
Answer:
show the number line
Step-by-step explanation:
Number of people < (should be smaller than or equal to but I don't have that button on my keyboard) (100-7) / 15.50
103/15.50 = 6.64516...
You can't have .645 of a person, so you must round down. Therefore, she can bring 6 people including herself.
