<span>The best way is to find the areas of the bases and the lateral faces separately and add them.
Let's start:
Base area = 14 x 4 = 56
Area of rectangle = 6 x 14 = 84
Area of second rectangle = 8 x 14 = 112
Area of slanted rectangle = 4.47 x 14 = 62.58
Now there are two sides remaining which includes triangles. Seperate the triangles from them and you will be left with 2 small rectangles on the front and back and also two triangles.
Area of two small rectangles = 2( 4 x 6) = 48
Area of two triangles = 4 x 2 = 8
Now add them all,
we get ====> 370.58 Square units</span>
I don’t see any question.
Ni : Zn: Cu = 7:2:9 =7x : 2x : 9x
7x+2x+9x = 3.8
18x=3.8
x=3.8/18=1.9/9≈0.21
Ni: 7x=7*0.21=1.47 ≈1.5 kg
Zn: 2x=2*0.21=0.42≈0.4 kg
Cu: 9x=9*0.21=1.89 ≈1.9 kg
Check 1.5+0.4+1.9 =3.8 True
Draw a right triangle ABC so that m∠C = 90°
The lengths are:
Side a is opposite ∠A,
Side b is opposite ∠B,
Side c (the hypotenuse) is opposite ∠C
Because cos A = x, therefore
x = b/c => b = cx (1)
Because sin A = y, therefore
y = a/c => a = cy (2)
By definition,
tan A = a/b
= (cy)/(cx)
= y/x
Answer: b. y/x
