I don't know how to answer this because i don't know the other numbers. But I can tell you to find a missing angle all the angles must add up to 180. So just add the other numbers and subtract the answer from 180 then you should get an answer.
8/5
We have to just divide.
Here 1 is the quotient while 3 is the remainder when 8 is divided by 5.
So, 8/5 is also equal to 1 3/5.
Hope This Helps You!
Answer:
58 in^2
Step-by-step explanation:
The area of one face of the 3" cube is (3 in)^2 = 9 in^2. Then the 6 faces of that will have an area of ...
6·9 in^2 = 54 in^2
The area of the top of the paperweight is unaffected by the area of the added cube: the area the smaller cube covers is exactly the same as its exposed top area. So, the net effect of the added 1" cube is to increase the total area by that cube's lateral area: 4 faces at 1 in^2 for each face, a total of 4 in^2.
Then the total surface area of the paperweight is ...
54 in^2 + 4 in^2 = 58 in^2
