Answer: ![h=8.33\ cm](https://tex.z-dn.net/?f=h%3D8.33%5C%20cm)
Step-by-step explanation:
Given
The length of a cuboid is ![l=15\ cm](https://tex.z-dn.net/?f=l%3D15%5C%20cm)
breadth is ![b=12\ cm](https://tex.z-dn.net/?f=b%3D12%5C%20cm)
Total surface area is ![S.A.=900\ cm^2](https://tex.z-dn.net/?f=S.A.%3D900%5C%20cm%5E2)
Surface area is given by ![2(lb+hl+bh)](https://tex.z-dn.net/?f=2%28lb%2Bhl%2Bbh%29)
Insert the values
![\Rightarrow 900=2(15\times 12+15h+12h)\\\Rightarrow 450=225+27h\\\Rightarrow 225=27h\\\Rightarrow h=8.33\ cm](https://tex.z-dn.net/?f=%5CRightarrow%20900%3D2%2815%5Ctimes%2012%2B15h%2B12h%29%5C%5C%5CRightarrow%20450%3D225%2B27h%5C%5C%5CRightarrow%20225%3D27h%5C%5C%5CRightarrow%20h%3D8.33%5C%20cm)
The measure of angle b is 25°.
Solution:
Given data:
The "L" shape angle is a right angle.
Right angle is splitted by another line and two angles are formed.
One angle is 65° and the other angle is b.
Let us find the other angle b.
65° + m∠b = 90°
Subtract 65° from both sides of the equation.
m∠b = 90° – 65°
m∠b = 25°
Hence the measure of angle b is 25°.
I believe that it is A. It is the only one that makes sense. If you look at numbers 0.47 and 0.00047, the decimal point in 0.00047 is three more spaces to the left than 0.47. Hope this helps!
