Answer: This sample may be biased because he is only asking the bike riders when in reality there might be a majority of students who instead take an alternate form of transportation
Step-by-step explanation:
Answer:
m∠C = 90°
Step-by-step explanation:
Triangle BDC is a right triangle with the measure of angle D = 90°
By applying Cosine rule in the given triangle,
Since, Cosine of any angle in a right triangle is a ratio of Its adjacent side and Hypotenuse (Opposite side of the right angle)
CosC = 
CosC = 
CosC = 
C = 28.955
C = 29°
Therefore, m∠C = 29° will be the answer.
The sides of a real triangle satisfy the <em>triangle inequality</em>, which just says any two sides add up to more than the third. It's strictly more; if two sides add up to exactly the third that's called a <em>degenerate triangle</em>. It's not a real triangle because the vertices are three collinear points.
The triangle equality fails when the sum of the two smallest sides fails to exceed the the largest side.
A. 4+6=10, degenerate triangle, not a real triangle
B. 4+7>7, isosceles triangles are real, SELECT
C. 4+3<10, not a real triangle
D. 4+7=11, degenerate triangle again
