From the description given for the triangle above, I think the type of triangle that is represented would be a right triangle. This type of triangle contains a right angle and two acute angles. In order to say or prove that it is a right triangle, it should be able to satisfy the Pythagorean Theorem which relates the sides of the triangle. It is expressed as follows:
c^2 = a^2 + b^2
where c is the hypotenuse or the longest side and a, b are the two shorter sides.
To prove that the triangle is indeed a right triangle, we use the equation above.
c^2 = a^2 + b^2
c^2 = 20^2 = 10^2 + (10sqrt(3))^2
400 = 100 + (100(3))
400 = 400
Answer:
12. n = 8
13. t = 308
14. k = 5
Step-by-step explanation:
12. 2/3 = n/12
Multiply by 4 because 3×4 = 12
So, n = 8
13. 33/t = 3/28
Multiply by 11 because 3×11 = 33
So, t = 308
14. k/6 = 15/18
Multiply by 3 because 6×3 = 18
So, 3k = 15. k = 5
Answer:
15
Step-by-step explanation:
A complementary angle is a right angle split into two parts. Since 75 is one of the two parts, we subtract it from 90, giving us an answer of 15.
