Answer:
if it is multiple choice:
x=2
x=3
Step-by-step explanation:
Using the Sine Rule:-
20 /sin 45 = BC / sin 30
BC = 20 sin 30 / sin45
= 20 * 1/2 / 1 / sqrt2
= 20 * 1/2 * sqrt2
= 10 sqrt2 answer

Answer C
Answer:

Step-by-step explanation:
We have:
(1) two trapezoids with bases b₁ = 7cm and b₂ = 5cm and the height h = 4cm
(2) three rectangles 3 cm × 7 cm, 3 cm × 4 cm and 3 cm × 5 cm.
The formula of an area of a trapezoid:

Substitute:

Calculate the areas of the rectangles:

The Surface Area:

7.2301*10^4=
7.2301*10000=
72,301 people in 1997
7.5583*10^4=
7.5583*10000=
75,583 people in 1978
75583/72301=
1.05
It was 1.05x greater
