This is an impossible triangle. The rules for determining if a triangle is possible are:
1.) a+b>c
2.) a+c>b
3.) b+c>a
We notice that when sides b and c (5cm and 4cm) are added, they are not greater than side a, so this triangle is not possible.

Answer:
128.57 degrees
Step-by-step explanation:
To find the measure of an interior angle of a regular polygon with sides, we can use the formula:
To find the measure of an interior angle of a polygon with 7 sides, all we have to do is plug in 7 into the formula:
7 minus 2 equals 5, so the answer is
÷
180 times 5 is equal to 900, and 900 divided by 7 is approximately 128.57
From 10 to 23, all you do is write in radical form.
For example, number 10, the answer would be
The denominator, 5, goes on top of that radical sign and the 1 is the exponent of y. That's what you have to do for 10 to 23.
Now 24 to 39 is just the opposite. You change it to exponent form.
For example, number 24, the answer would be
For 40 to 47, you have to neutralize the negatives or get rid of it, so you have to use the rule of negative exponents.
For example, number 40, the answer would be
For 48 to 55, you use multiply it but when multiplying exponents, you have to add.
For example, number 48, the answer would be
You don't need to multiply the two 5s because they are the bases.
Hope this helps.
Use f and m for "female" and "male." Then f = m + 16, and f + m = d (total)
So now we have the system of linear equations
f = m + 16
f + m = d
We can eliminate f by subst. m + 16 for f in the second equation:
d-16
m + 16 + m = d, or 2m + 16 = d. Find m. 2m = d - 16, so that m = --------

Assuming that the male horses are either brown or black, and that 25% of these are brown, then the rest must be black. This number is
d-16

Answer:
The scale factor of dilation is 2.
Step-by-step explanation:
From the given information it is notices that the vertices of preimage are A(1, 4), B(3, 4), C(3, 1), and D(1, 1). The vertices of image are A'(2, 8), B'(6, 8), C'(6, 2) and D'(2, 2).
The scale factor is the ratio of distance of a image of a vertex from the center of dilation and distance of the vertex from the center of dilation.
The center of dilation is origin. So, the scale factor is
.... (1)
Distance formula:
Now, put these values in equation (1).
Therefore the scale factor of dilation is 2.
