Answer:
<em>The sale price of the washing machine is £207.50.</em>
Step-by-step explanation:
<u>Percentages
</u>
To find a percentage of a given number, the procedure is multiplying the percentage by the number and divide by 100.
Suppose the normal price of the washing machine was x before the discount. The discount is:
17% of x = 17/100 * x = 0.17x
This discount is given as £42.50, thus:
0.17x = £42.50
Solving:
x = £42.50/0.17
x = £250
The sale price is:
£250 - £42.50 = £207.50
The sale price of the washing machine is £207.50.
Hello,
Magnetude is the norm of the vector=V13
Polar angle=arctan(2/3) ==>33.69...°
Adjacent angles are supplementary
so the exterior angles = 180 - 84 = 96 segrees.
