Answer:
x=5
Step-by-step explanation:
We can use proportions to solve this problem. Put the side of the small triangle over the side of the large triangle.
9 15
------ = ----------
2x-1 3x
Using cross products
9*3x = 15(2x-1)
27x = 30x-15
Subtract 30x from each side
27x-30x = 30x-30x -15
-3x = -15
Divide by -3
-3x/-3 = -15x/-3
x = 5
1.20
2. a=10
3.b=10\
i believe those are the correct answers
4 2/3 because 3 times 4 = 12 so there would be 4 wholes and 2/3 left
B. Acute and isosceles
Since the angle is less than 90 degrees and it has two equal sides
Answer:
x-int= (18,0), y-int= (0,-6)
