You can use c^2 = a^2 + b^2 to solve for the length of the other leg. Just substitute the values to the variable then transpose to get the value of the missing variable.

Given: a = 13; c = 21
Required: b - other leg
Solution:
   c^2 = a^2 + b^2
 21^2 = 13^2 + b^2
   441 = 169 + b^2
  b^2 = 272
  <span>√b = 16.49
    b = 16.49 cm</span>

For a Right Angled Triangle, according to the Pythagoras Theorem, the square of hypotenuse is equal to the sum of squares of its two legs.

One leg is 13cm long, hypotenuse is 21cm long. Let the other leg be x cm. So, we can write:

21^{2} =13^{2} + x^{2} \\  \\ &#10;272= x^{2}  \\  \\ &#10;x= \sqrt{272} \\  \\ &#10;x=16.49

Rounding of to nearest hundredth, the length of other leg of the Triangle is 16.49

our bank granted you a single-payment loan of $31,000 for 45 days at an interest rate of 20%. Your bank charges ordinary interes
vfiekz [6]

Solution given:

R=rate=20%

T=time=45days =1month and 15 days =1 ½ months=⅛years

P=Principal=$31000

since bank gives/takes compound interest

so

interest=P((1+R/100)^T-1)

=31000((1+20/100)^⅛-1)=$714.6
