If I remember right, each column can only go up to 60. so add up to seconds, anything over 60 stays and 1 carries over to the minutes. add those up, anything over 60 stays, and 1 carries over to degrees. then add those.
I got 53° 27' 5"
147 is the fiftieth term just multiply 3 by 50 and subtract 3
0.8 because .01 times 80.

Answer:
18.02 cm
Step-by-step explanation:
A diagonal makes a rectangle into two right triangles. So if we use the Pythagorean theorem we can find the hypotenuse which is the diagonals.
Remember, because we know the length and width, we know the two sides.
10^2 + 15^2 = c^2
100+225 = c^2
325 = c^2
18.027 ≈ c
So... hmmm if you check the first picture below, for 2)
we could use the proportions of those small, medium and large similar triangles like

now.. for 3) will be the second picture below
