missing angle 2: (3x - 1) º
Answer:
just know total angle sum is 180°
Step-by-step explanation:
[tex]52 + (15x + 3) + (3x - 1) = 180 \\ 52 + 3 - 1 + 15x + 3x = 180 \\ 54 + 18x = 180 \\ 18x = 180 - 54 \\ 18x = 126 \\ x = 7[/tex]
but give me a brainliest
Answer:
x = 7
Step-by-step explanation:
→ Find the sum of the angles
52 + 15x + 3 + 3x - 1 = 18x + 54
→ Wquate the expression to 180
18x + 54 = 180

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?
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.

168 units2
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
Therefore, Last option is correct.
Answer:
