Answer:
67°, 56° and 57°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180
7x + 7x + 1 + 8x + 3 = 180, that is
22x + 4 = 180 ( subtract 4 from both sides )
22x = 176 ( divide both sides by 22 )
x = 8
Then
∠ A = 8x + 3 = 8(8) + 3 = 64 + 3 = 67°
∠ B = 7x = 7(8) = 56°
∠ C = 7x + 1 = 7(8) + 1 = 56 + 1 = 57°
I take the second equation <span>x=5y+2
and substitute x in the first one:
means instead of
y = x + 5
y = (5y+2) + 5
I think you have to choose second answer

You can get this answer bye dividing the two numbers
9.125×10^2÷9.125×10^-3
Cancel the 9.125 to 9.125 and u will remind with 10^2÷10^-3
Exponent divided by exponent.
2-(-3)=5
10^5=100,000
9.125×10^-3 is 100,000 times less than 9.125×10^2
I think it will help
Total work amount
6 men * 14 days
84 men days
If it is done within 21 days, need x men
84 men days = x men * 21 days
x = 84/21 men
x = 4 men
The answer is B. because overall he ran 2 miles.
