Answer:
<A = 35degrees
<B =90degrees
<C = 55degrees
Step-by-step explanation:
Given the ratios of a triangle as 7:18:11
Total ratio = 7+18+11
Total ratio = 36
Since the smallest angle is 35degrees, hence <A = 35degrees
Get angle B;
<B = 18/36 * 180 (sum of angle in a triangle is 180degrees)
<B = 1/2 * 180
<B = 90degrees
Get angle C;
<C = 11/36 * 180
<C = 11 * 5
<C = 55degrees
Hence the value of A, B and C are 35, 90 and 55 degrees repectively
By the fundamental theorem of algebra, we can write
Expanding the right hand side, we get
We want 
to be an integer, which means 
must also be integers. This means must be factors of 10. There are several possibilities:
So there are 4 possible values for : -11, -7, 7, and 11.
Answer:
6. yes they are congruent, they are exactly the same shape and size
7. no they are not congruent, they are different sizes
8. they are congruent, they have the same shape and size
Step-by-step explanation:
Answer:
The range is all real numbers, because it's a vertical line, and the domain is -2 because it's a vertical line with -2 as it's only x.
