Answer:
D. $24.75
Step-by-step explanation:
24.75 - 4.75 - 1.65 = 18.35
Answer: (-2,-1)
Step-by-step explanation:
A and B are the endpoints and we know that to find the midpoint, we need to find the average between the x and y values.
The x coordinate of A plus the x coordinate of B has to equal 0. We can represent that by the equation
now solve for x to find the x coordinate of B by first multiplying both sides by 2.
x + 2 = 0 Subtract 2 from both sides
-2 -2
x = -2
So the x coordinate is -2 now find the y coordinate using the same method.
Multiply both sides by 2
-5 +y = -6 Add -5 to both sides
+5 +5
y = -1
The y coordinate is -1
so the coordinates of B is (-2,-1)
Answer:
12 cm
Step-by-step explanation:
Well first we can cut the triangle in half and use the Pythagorean theorm
a^2+b^2=c^2
In this case we are going to be doing c^2-a^2=b^2
10^2-8^2=b^2
(10*10)-(8*8)=b^2
100-64=b^2
36=b^2
Now we just square root 36 (what number times itself is 36)

b=6
Since half of the one side equals 6 (DC) then the length of AC is 12!
Answer:
The angle yo measures 40º.
Step-by-step explanation:
Given that the sum of yo and 50 ° is a right angle, to find the value of yo the following calculation must be performed, knowing that a right angle measures 90 °:
50 + yo = 90
yo = 90 - 50
yo = 40
Therefore, the angle yo measures 40º.
