Answer:
1. Yes
2. They could change the 60° angle into a different one.
Step-by-step explanation:
1. Two triangles are the same if they share two side lengths with the same angle between them.
2. Since the triangles are equal if they share two side lengths with the same angle between them, if they changed the angle between 3 and 5, it'd no longer be the same triangle.
Answer:
The original number is 90.8
Step-by-step explanation:
we know that
Let
x -----> the original number
The original number multiplied by 1.09 must be equal to 99
so
Solve the linear equation for x
Divide by 1.09 both sides
80 minutes or 1 hour and 20 minutes. 5 x 2 = 10. If it takes 40 minutes for 5 miles, than 40 x 2 = 80.
Answer:
C. a = 6 , b = 2√10
Step-by-step explanation:
Similarity triangles so
a/2 = 18/a
a^2 = 36
a = 6
b^2 = 2^2 + 6^2
b^2 = 4 + 36
b^2 = 40
b = 2√10
Answer
a = 6 , b = 2√10
Step-by-step explanation:
0.25 Is the rate and x is how many minutes
