83.21

You find it by moving the decimal places two times to the right.

7/4pi multiplied by 180/pi give you about 97 degrees when you calculate it.

When two equal forces are inclined at an angle 2a their resultant is twice as great as

swat32

Step-by-step answer:

Referring to the attached diagram, the resultant of two forces each with magnitude F and inclined to each other at 2a equals

Ra = 2Fcos(a) ..............................(1)

Similarly, the resultant of two forces each with magnitude F and inclined to each other at 2b equals

Rb = 2Fcos(b)..............................(2)

We are given that

Ra = 2Rb ....................................(3)

Substitute (1) & (2) in (3) gives

2Fcos(a) = 2(2Fcos(b))

Expand

2Fcos(a) = 4Fcos(b)

Simplify

cos(a) = 2 cos(b) QED

Note: Please note that you might have a faster response if you posted this question in the physics or the (new) Engineering section.

Have a nice day!

Barney has 16 1/5 yards of fabric. To make an elf costume, he needs 5 2/5 yards of fabric. How many costumes can Barney make?

9966 [12]

To get the answer, first, you need to turn them into decimals
16 1/5 =16.2 and 5 2/5 =5.4
then all you need to do is to divide the numbers
16.2 divided by 5.4 equals to 3
so the answer is 3
