Answer:
x= 20
Step-by-step explanation:
The total amount of degrees in a triangle is 180. The equation we can pull from this is x+x+30+110= 180. Now we can simplify and combine like terms. x+x= 2x. 30+110 is 140. Now move the constant, 140 to the right. 180-140 is 40. Lastly, divide x and 40 by 2 to get the final answer of 20.

Answers
Answer: Last option is correct.
Since we have given that
Dimension of central rectangle is 6 units by 7 units
So, Area of central rectangle is given by
Dimensions of upper and lower rectangle are as follows:
Length = 5 units
Breadth = 7 units
Area of upper and lower rectangle is given by
Similarly, dimensions of two triangles are as follows:
Height = 4 units
Base = 6 units
So, Area of two triangles is given by
Hence, Total surface area of the net of an isosceles prism is given by

It would take 48 days for 5 men to build a house.
(a) How much longer would it take if only 4 men built the house?
Answers
The number of days required to build a house by 4 men which is made by 5 men is 48 days is 60 days.
What is the relation between work and time?The total time taken is inversely proportional to the rate of work. If a unit of work is done in total n number of days, then the total work done in a day can is,
W=(1/n)
It would take 48 days for 5 men to build a house. Thus, the work done by one man in one day is,
W=1/(48*5)
W=1/240
Thus, one man take 240 days to build a house. The time it takes when only 4 men works to build the house,
t=240/4
t=60
Hence, the number of days required to build a house by 4 men which is made by 5 men is 48 days is 60 days.
