1 yard = 12 inches, so 9 yards would be 108 inches.
Answer:
- Angle-Angle-Angle(AAA)
- Side-Angle-side(SAS)
Step-by-step explanation:
Let's see what is similar in both triangles
So Angle-Angle-Angle similarly theorem verified
So Side-Angle-side or Side-Side-Side similarity theorem verified
Answer:
A)Triangle B is a reflection of Triangle A across the x-axis. Triangle C is not a reflection of Triangle A.
Step-by-step explanation:
I believe this is the correct answer because Tringle B does reflect Triangle A across the x-axis (----------) and ofcourse Triangle C is not a reflection of A
Answer:
1) The terminal side lies in quadrant 2
2) cosФ = -15/17
3) tanФ = -8/15
Step-by-step explanation:
1) First, we should realize that since sinФ = 8/17, it is positive. Thus, Ф must be in quadrants 1 or 2. And since cosФ is negative, Ф must be in quadrant 2 because cos, sin, and tan are all positive in quadrant 1
2) Next, we must realize that the sides given are a 8-15-17 right triangle. And in this case, since sinФ = 8/17, cosФ should be 15/17. But since cosФ is negative, cosФ = -15/17
3) Lastly, tanФ is opposite/adjacent. Since opposite of Ф is 8 and adjacent of Ф is 15, then tanФ should be 8/15, but since Ф is in quadrant 2, then tanФ is -8/15
