Answer:
42.1
Explanation step-by-step:
Working out the lenght of the blue-dashed line:
SOH
47 is the Hypotenuse.
the blue line is the adjacent.
adjacent= Cos(30) x47
adjacent= 40.7
Working out x :
40.7 is the opposite this time.
x is the adjacent.
x = 40.7/ Tan(44)
x = 42.1
7x^2
63/9 = 7, x^4/x^2 = x^2
12
area = × base × height
= x 3xy² × 8x³ = 12
= 12
Answers:Architects always
15.8
Step-by-step explanation:
