So for question 7 part A the picture will be a triangle similar to the the one that shows the umbrella's height. But the base will be 40 and the height will be 130.
for part B the angle of depression can be found using the trigonometric function of tangent.
tan x = 40/130
tan^-1 (tan x) = tan^-1 (40/30)
x = 17 degrees
I hope i am right

Answer:
a) The discounted prince is 70% of the full price.
b) 32.5 €
Step-by-step explanation:
a) If the full price is 100%, then you subtract 30% which is the discount and you get 70 %.
b) 22.75 is 70% of 32.5
240 minutes is equal to 4 hours.
Answer:
17
Step-by-step explanation:
To find the hypotenuse, you would use the Pythagorean theorem.
We can plug 8 and 15 into A and B\
We can simplify this to
64+225=
289 =
To get C by itself not squared, we can do the square root of both sides.
If we simplify, we get
17 = C or C = 17
Therefore the length of the hypotenuse is 17.
