Make use of the fact that side lengths in similar triangles are proportional.
.. 30/18 = (20 +x)/20
.. 20*(30/18) -20 = x . . . . multiply by 20, subtract 20
.. 33 1/3 -20 = x . . . . . . . . evaluate the product
.. 13 1/3 = x
Answer:
£1756.70
Step-by-step explanation:
2155.45 * .185 = 398.75825
21.55.45 - 398.75825 = 1756.69175
Hope this helps
Answer:
d = 2750/Cos 48
Step-by-step explanation:
We need the value of the angle from the vertical axis
90 - 42 = 48°
We are trying to find the distance d which is the Hypotenuse of the right angled triangle formed.
The relationship between the adjacent and hypotenuse is help by the cosine of the angle between them
such that
Cos 48 = Adj/Hyp
Cos 48 = 2750/d
d Cos 48 = 2750
d = 2750/Cos 48
