Answer:
93.99
Step-by-step explanation:
sin rule is:
sin A ÷ a = sin B ÷ b = sin C ÷ c
A B C are angles
a b c are the lengths opposite to each angle
to find angle opposite to x:
180- (90+57) = 33°
180: sum of angles in a traingle
90: since its a right angle traingle
to find x:
sin 57 ÷ 41 = sin 33 ÷ x
rearrange:
x= (sin 33 x 41) ÷ sin 57
x= 93.99 (2 d.p/2 decimal places)
Answer:

Step-by-step explanation:
Given 
Let 
Interchange x and y

Solve for y, by first squaring both sides


Hence

The last choice is correct
Answer:
B
Step-by-step explanation:
Area of pool = l × b
l = 6x and b = 3x - 5
Area = 6x(3x - 5)
Area = 18x² - 30x
