Answer:
Step-by-step explanation:
Use midpoint formula to find the coordinates of each midpoint.
(x, y) = (½ (x₁ + x₂), ½(y₁ + y₂))
The coordinates of B and C are given.
Coordinates of D:
(x, y) = (½ (4 + 2), ½(6 + -2))
(x, y) = (3, 2)
Coordinates of E:
(x, y) = (½ (4 + -2), ½(6 + -4))
(x, y) = (1, 1)
Slope of DE:
m = Δy / Δx
m = (2 − 1) / (3 − 1)
m = 1/2
Slope of BC:
m = Δy / Δx
m = (-2 − -4) / (2 − -2)
m = 1/2
Therefore, DE is parallel to BC.
Answer: AC=4.15
Step-by-step explanation:
To solve this problem you must apply the prccedure shown below:
1. You know that the triangle is a right triangle.
2. Therfore, you can calculate the lenght AC as following:
Where:
opposite=AC
adjacent=8.9
3. When you solve for AC and substitute these values you obtain the following result:
If you would like to know how many dollars is the increase, you can calculate this using the following steps:
7% of $45 = 7% * 45 = 7/100 * 45 = $3.15
Result: The increase is $3.15.
The answer is reflexive property of congruence
Answer:
$93
Step-by-step explanation:
If he earns $7.75 a day, and he walks dogs for 12 days, you just have to multiply 7.75 by 12, which is 93. That means he gets $93.
