Answer:
No, the distance between points A and F was used to create circle H.
Step-by-step explanation:
In the given example the points F and G are the radius of the circle H. The distance from point A to point F is used to draw the circle H. The center point for circle H is point A. The circle is the copied and the angles are used to create another circle.
Answer:
Step-by-step explanation:
To solve this, we are going to make an age table:
Age Now Age 10 years ago
Tanya
Elliot
Filling the in the Age Now column comes from the first sentence. If Elliot is 2 times Tanya's age and we don't know Tanya's age, then Tanya's age is x and Elliot's age is 2x:
Age Now Age 10 years ago
Tanya x
Elliot 2x
Filling in the Age 10 years ago column simply requires that we take their ages in the Age Now column and subtract 10 from each age:
Age Now Age 10 years ago
Tanya x x - 10
Elliot 2x 2x - 10
Since the question is How old is Elliot now based on the fact that 10 years ago....blah, blah, blah, we are using the ages in the 10 years ago column to write our equation. It says:
10 years ago, Elliot was 4 times as old as Tanya. Translated into mathspeak:
2x - 10 = 4(x - 10) and
2x - 10 = 4x - 40 and
-2x = -30 so
x = 15. That means that Elliot is 30 and Tanya is 15
Its 23. you just add them together
Answer:
1. I, II,
Step-by-step explanation:
<em>I. Diagonals are perpendicular bisectors of each other </em>
Yes, because 4 sides are congruent so it makes the two diagonals perpendicular bisectors
<em>II. Diagonals bisect the angles from which they are drawn </em>
Yes, That is the property of the diagonal!
<em> III. Diagonals form four congruent isosceles right triangles. </em>
No, only two pairs of right triangles are congruent and sometime the side of each pair are different to each other.
Hence, we choose I and II
