Solve 700^2+100^2-2*100*200cos(05^circ)

$$700 ^ { 2 } + 100 ^ { 2 } - 2 \times 100 \times 200 \cos ( 05 ^ { \circ } )$$

Evaluate

$$460000$$

Solution Steps

Calculate 700 to the power of 2 and get 490000.

$$490000+100^{2}-2\times 100\times 200\cos(0\times 5)$$

Calculate 100 to the power of 2 and get 10000.

$$490000+10000-2\times 100\times 200\cos(0\times 5)$$

Add 490000 and 10000 to get 500000.

$$500000-2\times 100\times 200\cos(0\times 5)$$

Multiply 2 and 100 to get 200.

$$500000-200\times 200\cos(0\times 5)$$

Multiply 200 and 200 to get 40000.

$$500000-40000\cos(0\times 5)$$

Multiply 0 and 5 to get 0.

$$500000-40000\cos(0)$$

Get the value of \cos(0) from trigonometric values table.

$$500000-40000\times 1$$

Multiply 40000 and 1 to get 40000.

$$500000-40000$$

Subtract 40000 from 500000 to get 460000.

$$460000$$
