First calculate th feet of lace she haven't used.
9 - 3 = 6 ft
now we can convert feet into yard. we can divide the amount into 3 because it says 3ft is 1yrd
6 / 3 = 2 yards
Round 2.81 to 2.8 and 3.72 to 3.7. Add both together to get 6.5
The answer is 3x+15 hope this helps :)
Answer:
x = 18 and y = 6√10
Step-by-step explanation:
First using pythagoras theorem on the small triangle
h² = 6² + 2²
h² = 36 + 4
h² = 40
h= √40
h = √4 * 10
h = 2√10
Using the similarity theorem;
y/2√10 = 6/2
y/√10 = 6
y = 6√10
To get x we will use the pythagoras theorem
y² = x²+6²
(6√10)² = x² + 36
360 = x² + 36
x² = 360 - 36
x² = 324
x = 18
Hence x = 18 and y = 6√10
