Answer:
x ≈ 1.1868143
Step-by-step explanation:
They relate to each other because you have to find the Base and Height
;
2 × 5 × sin( π / 12 ) = 10 × sin ( π / 12 ) ;
π/12 = ( 180° ) / 12 = 15°.
<span>
But, sin ( π/12 ) </span>
<span>= sin 15° </span>
<span>= sin ( 45° - 30°) </span>
<span>= sin 45°· cos 30° - cos 45°· sin 30° </span>
<span>= (1/√2)·(√3 /2 ) - (1/√2)·(1/2) </span>
<span>= ( √3 - 1 ) / (2√2) = </span>

Finally, ( 2.5 ) × ( 2.4 - 1.4 ) = 2.5 cm ;
Answer:
- a) x+y
- b) 2x+y
- c) -x
- d) x+y+1
- e) y-x
- f) x/2
Step-by-step explanation:
The applicable rules of logarithms are ...
log(ab) = log(a) +log(b)
log(a^b) = b·log(a)

Area of the triangle at the top=1/2basexheight
1/2x10x 2= 10
Area of rectangle =length xwidth
9x10=90
Total area =area of triangle +area of rectangle
90+10=100m^2
