Answer:
a) 16.25 centimeters
b) 6.8 centimeters
Step-by-step explanation:
We can set up a proportion for both of these problems.
a) Look at the longest side of each triangle. We can set up a fraction: 7.2/18. We can also set up a fraction for XZ and PR:
6.5/x
x represents the length you're trying to find.
Since the triangles are similar, we have an equation:
7.2/18=6.5/x
Cross multiply
16.25
XZ is 16.25 centimeters long.
b)
We can do same thing:
7.2/18=x/17
Cross multiply
6.8
QR is 6.8 centimeters long.
Hope this helps!
Answer:
You would explain what I did in the step by step explanation.
Step-by-step explanation:
There are three types of triangles: equilateral, isosceles, and scalene. An equilateral triangle has all 3 sides congruent, an isosceles has only 2 sides congruent, and a scalene has no sides congruent. So, if the triangle has marked sides congruent, or you have found some sides congruent, then you look at the amount of sides congruent, and then you can find the type of triangle. For example, if you have a triangle called ABC, and AB and BC are congruent but AC is not, then it is Isosceles because 2 sides are congruent. You would explain the 3 triangle definitions to your friend.
Answer:
AD = 12 units
Step-by-step explanation:
AD = CD
so
4x = 10x-18
subtract 10x from both sides to get:
-6x = -18
divide each side by -6 to get:
x = 3
insert x into your problem and you get 4(3) which equals 12
To calculate the area of the black material on the flag, we need the shape and the dimensions of the black material itself.
<em>Since the question is incomplete, as the dimension of the flag and the dimension of the black material are not given, I will provide a general explanation</em>
<em />
Assume the shape of the black material is a rectangle.
The area will be calculated as:
Take for instance;
The area is:
Assume the shape of the black material is a square.
The area will be calculated as:
Take for instance;
The area is:
Assume the shape of the black material is a triangle
The area will be calculated as:
Take for instance;
The area is:
So, in general.
You need to first get the shape of the black segment on the flag, then calculate the area using the appropriate formula.
