Answer:

  51°, 129°

Step-by-step explanation:

The ratio of the sides is the tangent of the angle a diagonal makes with the side of the rectangle. The smaller such angle will be

  arctan(12.4/26) ≈ 25.5°

The smaller of the angles between the diagonals will be twice this value, or 51°. Its supplement is the larger angle between the diagonals, 129°.

What is 12.496 rounded to a whole number. what is 2.90 rounded to a whole number
otez555 [7]
A whole number is a number that is whole as in 1,2,3,4,etc, they don’t have decimals. To find the whole number for these questions you must look at the places (hundreds, thousands, ten thousands.) I was always told a trick which is 4 or less let it rest, 5 or more let it sore. (Basically if it’s less than 4 then decrease it, if it’s higher than increase it.)

12.496 = 13
2.90 = 3

Your answers are 13 and 3.

Matthew is designing a new board game, and is trying to figure out all the possible
icang [17]

The computation shows that there are 8640 combinations.

<h3>How to compute the value?</h3>

From the information, we are to find the combination when he rolls a cube that has six sides labeled 1 to 6, spins a spinner with three equal-sized sections labeled Walk, Run, Stop, and flips a coin.

This will be:

Cube = 6

Spinner = 3

Coin = 2

The combination will be:

= 6! × 3! × 2!

= 8640 ways

Therefore there are 8640 combinations.
