Answer:
5x^2-x-4
Step-by-step explanation:
Combine the terms.
Use proportions because we know that the triangles are similar.
Cross multiply.
20x=28×5
x=7
answer: 7
Answer:
2
Step-by-step explanation:
sin 17° = x/7
(sin 17°) 7 = (x/7)7
x = sin 17° (7)
x = 0.292371704722737 (7)
x = 2.046601933059157
x ≈ 2
Answer : AB and DE are the secants

Answer:
18=x*.20
15=x*.25
12=x*.30
24=x*.40
39=x*.60
78=x*.30
Step-by-step explanation:
To solve for x on each, divide the number on the left of the equal side by the number x is being multiplied by. For example, 18/.20=x
